Question

The student council at Greenwood High School is making T-shirts to sell for a fundraiser, at a price of $18 apiece. The costs, meanwhile, are $10 per shirt, plus a setup fee of $40. Selling a certain number of shirts will allow the student council to cover their costs. How many shirts must be sold?

Answer 1

Costs are $490

49 shirts are sold

98 + 8x = 10x

98 = 2x

49 = x

98 + 8(49) = $490 in costs

49 shirts sold

Step-by-step explanation:

98 + 8x = 10x

98 = 2x
