Suppose your school is selling magazine subscriptions. Each subscription costs $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 subscription that can be sold to earn a profit of $200?

9.1 is incorrect, that's not enough to even earn 100 dollars. Lets go through it
they need to make 218 dollars. 200 for the profit and 18 for the payment.
each sale gives them 10 dollars because they get half of 20.
so 10x=218
x=21.8
you can't sell 21.8 subscriptions. you can sell 21 or 22. but selling 21 subscriptions doesn't make you a 200 dollar profit, so the answer is 22.
