Question

Ben works at a mobile phone store, where he earns a flat $80 for each 8-hour shift. He also earns a commission of $20 for each phone that he sells. If e stands for Ben's earnings and m is the number of mobile phones he sells, which of the following equations describes the amount of money that he earns in one shift?Question 5 options:A) e = m + 80B) e = m + 100C) e = –20m + 80D) e = 20m + 80

Answer 1

fixed earnings = $80 ( for 8 hour shift)

Number of mobile phones he sells = m

Commision for each mobile phone sold = $20

Amount he earns in 1 shift (e) = flat + number of phones* commision

e = 80 + 20m

e= 20m + 80 (D)
