Shental's Magazine Fundraiser Totals $1,225

Shental is doing a fantastic job raising money for the local animal shelter by selling magazine subscriptions! It's wonderful to see young people taking initiative to help our furry friends. She's offering two types of yearly subscriptions: a story magazine for $12.50 and a puzzle magazine for $14. So far, she has managed to raise an impressive total of $1,225. This is a significant amount, and it really shows her dedication and the generosity of the community supporting her efforts. Let's dive into how we can figure out the exact number of each type of subscription she sold, based on this total amount raised. This kind of problem is a classic example of using algebra to solve real-world scenarios, making math both practical and engaging.

Understanding the Variables and the Goal

To get a clear picture of Shental's fundraising success, we need to break down the information given. We know the price of each magazine subscription: the story magazine costs $12.50 per year, and the puzzle magazine costs $14 per year. We also know the total amount of money Shental has collected, which is $1,225. Our main goal here is to determine the specific number of story magazine subscriptions and puzzle magazine subscriptions she sold. This isn't just about finding numbers; it's about understanding the relationship between the quantities and the total amount. By solving this, we can give Shental a complete picture of her sales, which can be incredibly motivating for her and perhaps even help her plan future fundraising events. This is where the power of mathematics shines, turning a set of numbers into a clear and actionable insight. We're essentially trying to solve a puzzle using the tools of mathematics, much like the puzzle magazines Shental is selling!

Setting Up the Algebraic Equation

Let's use some simple algebra to figure this out. We can assign variables to the unknowns. Let 's' represent the number of yearly story magazine subscriptions sold, and let 'p' represent the number of yearly puzzle magazine subscriptions sold. Now, we can translate the information into an equation. The total money raised from story magazines is the price per subscription ($12.50) multiplied by the number of subscriptions sold (s), so that's 12.50s. Similarly, the total money raised from puzzle magazines is the price per subscription ($14) multiplied by the number of subscriptions sold (p), which gives us 14p. Since the total amount raised is $1,225, we can set up our equation as follows: 12.50s + 14p = 1225. This single equation represents all the financial information we have. It's a linear equation with two variables, and it's the key to unlocking the number of each type of magazine subscription sold.

Solving the Equation: Finding Possible Combinations

Now, the interesting part: solving the equation 12.50s + 14p = 1225. Since we have one equation with two variables, there might be multiple combinations of 's' and 'p' that satisfy this equation. However, in a real-world scenario like this, the number of subscriptions must be whole numbers (you can't sell half a magazine subscription!). This constraint helps us narrow down the possibilities. We're looking for non-negative integer solutions for 's' and 'p'. We can try to simplify the equation or use a systematic approach to find these solutions. For instance, we can try plugging in possible values for 'p' (starting from 0 and increasing) and see if we get a whole number for 's'. Or, we can rearrange the equation to solve for one variable in terms of the other. For example, we could solve for 's': s = (1225 - 14p) / 12.50. Then, we would test values of 'p' until (1225 - 14p) is not only divisible by 12.50 but also results in a non-negative whole number for 's'. This process might take a bit of trial and error, but it's a very effective way to find the specific numbers that fit Shental's fundraising results. It's like a treasure hunt for numbers!

Calculating the Number of Subscriptions

Let's get down to the actual calculation. We have the equation 12.50s + 14p = 1225. To make calculations easier, we can multiply the entire equation by 2 to get rid of the decimal: 25s + 28p = 2450. Now, we need to find integer values for 's' and 'p' that satisfy this. Let's try a systematic approach. We can rearrange the equation to solve for 's': 25s = 2450 - 28p, so s = (2450 - 28p) / 25. Since 's' must be a whole number, (2450 - 28p) must be divisible by 25. Also, 's' and 'p' must be non-negative. Let's test some values for 'p':

• If p = 0, then s = 2450 / 25 = 98. This is a valid solution: 98 story subscriptions and 0 puzzle subscriptions. Total raised: (98 * 12.50) + (0 * 14) = 1225 + 0 = 1225.
• If p = 1, 2450 - 28(1) = 2422, not divisible by 25.
• We notice that 28p must end in a 0 or a 5 for 2450 - 28p to be divisible by 25 (since 2450 ends in 0). For 28p to end in 0 or 5, 'p' must be a multiple of 5 (as 28 ends in 8).

Let's try p = 5: s = (2450 - 28*5) / 25 = (2450 - 140) / 25 = 2310 / 25 = 92.4. Not a whole number.

Let's try p = 10: s = (2450 - 28*10) / 25 = (2450 - 280) / 25 = 2170 / 25 = 86.8. Not a whole number.

Let's try p = 25: s = (2450 - 28*25) / 25 = (2450 - 700) / 25 = 1750 / 25 = 70. This is a valid solution: 70 story subscriptions and 25 puzzle subscriptions. Total raised: (70 * 12.50) + (25 * 14) = 875 + 350 = 1225.

Let's try p = 50: s = (2450 - 28*50) / 25 = (2450 - 1400) / 25 = 1050 / 25 = 42. This is a valid solution: 42 story subscriptions and 50 puzzle subscriptions. Total raised: (42 * 12.50) + (50 * 14) = 525 + 700 = 1225.

Let's try p = 75: s = (2450 - 28*75) / 25 = (2450 - 2100) / 25 = 350 / 25 = 14. This is a valid solution: 14 story subscriptions and 75 puzzle subscriptions. Total raised: (14 * 12.50) + (75 * 14) = 175 + 1050 = 1225.

Let's try p = 87.5 (not a whole number for p, just checking the limit for p where s becomes 0). Maximum p value would be when 2450 - 28p = 0, so p = 2450 / 28 = 87.5. Since p must be a whole number, the maximum integer value for p is 87. Let's check p = 85. s = (2450 - 28*85) / 25 = (2450 - 2380) / 25 = 70 / 25 = 2.8. Not a whole number.

So, the possible combinations of subscriptions sold are: (98 story, 0 puzzle), (70 story, 25 puzzle), (42 story, 50 puzzle), and (14 story, 75 puzzle). Without more information, any of these combinations could be the actual sales figures.

Celebrating Shental's Achievement

It's truly inspiring to see Shental putting in so much effort for a great cause like the animal shelter. She has not only managed to raise a substantial amount of money but has also provided us with an excellent real-world problem to solve using mathematics. Each of the possible combinations we found represents a successful fundraising outcome. For example, if Shental sold 70 story subscriptions and 25 puzzle subscriptions, she would have raised $875 from story magazines and $350 from puzzle magazines, totaling exactly $1,225. Alternatively, if she sold 42 story subscriptions and 50 puzzle subscriptions, she would have raised $525 from story magazines and $700 from puzzle magazines, again totaling $1,225. The same applies to the other two combinations. This demonstrates the flexibility and power of mathematical modeling; it can help us understand scenarios even when there isn't a single, unique answer without additional constraints. Shental's fundraising is a success regardless of which combination of subscriptions led to the total, and the animals at the shelter will certainly benefit from her hard work.
