Question

Alexa works for an ice cream cart vendor . She receives $28 for taking the cart out for a shift plus a commission of $0.15 for each item she sells . Alexa worked a shift Saturday and earned $ 49.30 . Write equation to solve for x, the number of items Alexa sold?

Answer 1

Answer:

28 + 0.15x = 49.30

0.15x = 49.30 - 28

0.15x = 21.3

divide both sides by 0.15

x = 21.3/0.15

x = 142
