Question

Two people worked on a car. The first person charged $ 85 per hour, and the second person charged $ 120 per hour. The people worked for a combined total of 15 hours, and together they charged a total of $ 1450 . How long did each person work?

Answer 1

Answer:

10 hours for $85/hour

5 hours for $120/hour

Step-by-step explanation:

85t + 120(15-t) = 1450

85t - 120t = 1450 - 1800

-35t = -350

t = 10

15 - t = 5
