Question

4. During a long weekend, Devon paid a total of x dollars for a rental car so he could visit his family. He rented the care for 4 days at a rate of $36 per day. There was an additional charge of $0.20 per mile after the first 200 miles.

a. Write an expression to represent the amount Devon paid for additional mileage.

b. Write an expression to represent the number of miles over 200 miles that Devon drove.

c. How many miles overall did Devon drive overall if he paid $174 for the car rental? Show work.​

Answer 1

A)

c = 0.20m + 144

Where c is total cost and m is miles driven.

B)

c = (200 + 0.20m) + 144

C)

174 = 0.20m + 36x4

174 = 0.20m + 144

30 = 0.20m

30/0.20 = m

m = 150+200

m = 350miles

Hope that helps
