Plainfield Community Center is buying new seating for their building. They want to purchase a combination of stools and chairs. Stools cost $50 and chairs cost $65. The center cannot spend more than $3000. Which inequality represents all possible combinations of s stools and c chairs?

a) 50s + 65c ≤ 3000

b)50c + 65s ≤ 3000

c) 50c + 65s ≥ 3000

d) 50s + 65c < 3000

A

Step-by-step explanation:

If you have s number of stools and c number of chairs, the price can be expressed as 50s + 65c. Since the question says you cannot spend more than 3000, you could spend less than or equal to 3000. So the inequality is 50s + 65c ≤ 3000.
