Not sure how to solve this:

Suppose your school is selling magazine subscriptions. Each subscription cost $20. the company pays the school half of the total sales in dollars. The school must also pay a one-time fee of $18. What is the fewest number of subscriptions that can be sold to earn profit of $200?

200/2 =100

100 + 18 = 118/20 = 5.9 = 6 subscriptions?

No, the question is asking for the FEWEST account of magazines sold to make $200 for the school.

-So we know that in order to make $200 for the school they must make an actually $400 profit because the company will take half of the money. But we must include the $18 fee.
So in reality the school will have to make a total of $418 to make a $200 profit. Now we just have to find calculate the amount of Magazines sold out of $418.

So 418/20= 20.9 magazines, but you must round to 21 because there's no such thing as selling .9 of a magazine.

So your answer is 21 subscriptions.

Work check:

21 magazines x $20= $420

$420 - $18 (the fee) = 402

$402 / 2 (since the company takes half the profit) = $201

School makes more than $200 profit?
Yes

You are selling magazines to raise money for your school. Each subscription you sell earns $8 for your school. How much money will you raise if you sell 20 subscriptions?

number of subscriptions =x

profit = (20/2) * x - 18
for a profit of 200,
10x - 18 = 200
10x = 218
x = 21.8
therefore, minimum number of tickets = 21

To solve this problem, you need to consider the profit that the school wants to earn and the costs involved in selling the subscriptions. Let's break it down step by step:

1. Find the total amount of money the school needs to earn in order to make a profit of $200. In this case, it is $200.

2. Determine how much money the school earns from each magazine subscription sold. From the information given, the school receives half of the total sales in dollars. Since each subscription costs $20, the school earns $10 per subscription sold.

3. Calculate the number of subscriptions needed to earn the desired profit by dividing the profit by the amount earned per subscription. In this case, it is $200 divided by $10, which gives you 20 subscriptions.

4. Consider the additional costs involved. In this case, the school must also pay a one-time fee of $18.

5. Add the one-time fee to the total cost of the subscriptions to find the minimum number of subscriptions required to cover the fee and earn the desired profit. In this case, it is $20 multiplied by 20 subscriptions plus $18, which equals $418.

So, to earn a profit of $200 after considering the costs, the school must sell a minimum of 21 subscriptions (since it can't sell fractional subscriptions).
