Question

Wilton drives an Uber. He charges $20 per hour. One passenger gave Wilton an additional tip of $10, which made the total he paid $90. How many hours did Wilton drive the passenger? Solve for the unknown quantity. (2 pts – 1 pt for correct answer, 1 pt for showing your work)

Answer 1

4 hours

Explanation:

He charges 20 bucks per hour, and a passenger gave him a ten dollar tip.

1. Remove the 10 dollar tip (Or it will throw you off, trust me)

2. Divide 80, Number with no tip, by the amount charged per hour, 20.

3. You get 4, so you know it is 4 hours
