Question

Roger gets $40 per day as wages and $4.50 as commission for every pair of shoes he sells in a day. His daily earnings goal is $112.

Write an equation to determine how many pairs of shoes, ppp, Roger must sell in a day to meet his daily earnings goal.
Find the number of pairs of shoes he must sell to meet his daily earnings goal.

Answer 1

Basic Pay = $40

Commission for 1 pair of shoes = $4.50

Let x be the number of shoes he needs to sell.

40 + 4.5x ≥ 112
4.5x ≥ 72
x ≥ 16

Answer: He must sell at least 16 pairs of shoes.

Answer 2

112=4.5p+40
