Suppose you work in a clothing store. Each week you earn $250 plus a commission equal to 2.5% of your sales. This week your goal is to earn no less than $350. Write and solve an inequality to find the amount of sales you must have to reach your goal.

Answer 1

p=pay, s=sales

p = 250 + .025s

you want at least 350 pay

p >= 350
250 + .025s >= 350
.025s >= 100
s >= 4000

so, sell at least $4000 -- get busy!
