Question

Roger gets $40 per day as wages and $4.50 as commission for every pair of shoes ne sells in a day. His daily
earnings goal is $112.
Write an equation to determine how many pairs of shoes, D, Roger must sell in a day to meet his daily earnings
goal

Answer 1

Answer:

Equation : y = 4.50D + 40

Number of pairs = 16

Step-by-step explanation:

It is given that:

Per day wage of Roger = $40

Commission on per pair of shoes = $4.50

Daily goal = $112

Number of pairs of shoes = D

Total earning = y

y = 4.50D + 40

112 = 4.50D + 40

4.50D = 112 - 40

4.50D = 72

Dividing both sides by 4.50

$\frac{4.50D}{4.50}=\frac{72}{4.50}\\D = 16$

Therefore,

Equation : y = 4.50D + 40

Number of pairs = 16
