Question

A carpenter makes and sells rocking chairs. The material for each chair costs $22.50. The chairs sell for $75 each. If the charpenter spends $420 on advertising, how many chairs must she sell to break even?

Answer 1

About 6 chairs

Explanation:

75x=22.50+420

75x=442.5

x=5.9

So about 6 chairs

Answer 2

8 chairs

Explanation:

Let x = number of chairs.

costs: materials for the chairs + advertising costs

costs = 22.5x + 420

income: sale price of each chair

income: 75x

Set the costs equal to the income.

75x = 22.5x + 420

52.5x = 420

x = 8

Answer: 8 chairs
