Question

1. A school booster club is selling

T-shirts. The silk-screening company
is selling shirts to the boosters for
$3 each, plus a one-time fee of $150
to cover supply costs. If the boosters
want to make at least $300 in profits
and they sell a shirt for $12, how
many shirts do they need to sell?

Answer 1

Explanation:

sales - expenses = profit

lets x represent number of shirts sold

12x - (3x + 150) > = 300

12x - 3x - 150 > = 300

9x - 150 > = 300

9x > = 300 + 150

9x > = 450

x > = 450/9

x > = 50 <== they would need to sell at least 50 shirts
