P = 0.5*20x - 18 = 200
10x - 18 = 200
10x = 218
X = 21.8 or 22 Copies.
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?
