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, roger must sell in a day to meet his daily earnings goal.

40 + (4.50n) = $112

Step-by-step explanation:

Roger gets wages per day = $40.00

He earns commission for every pair of shoes he sells in a day = $4.50

His daily earning goal is = $112

Let the number of shoes he sells 'n'

The equation will be

40 + (4.50n) = $112

4.50n = 112 - 40

4.50n = 72

n = 72 ÷ 4.50

n = 16

He has to sell 16 pair of shoes.
