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?

I did it 20y+18=200
and got 9.1 which is aprox 9 subscriptions is that correct?
if not please tell me what the correct answer is thank you for your help :]

let x = number of subscriptions

(20x / 2) - 18 >= 200

10x - 18 >= 200

10x >= 218

x >= 21.8

22 subscriptions
