Question

E-Z Rentals charges a daily fee of $30 for each car rental and adds an additional chargeof $0.10 per mile driven.A. Write an equation to determine the total cost (c) for renting a car for one day whiledriving m miles.B. What is the total cost for the day if 275 miles were driven that day?C. If the total bill for the day was $48, then how many miles were driven that day?

Answer 1

A. c = 30 + 0.1m

where c is the cost (in $) and m are miles driven

B. Substituting with m = 275:

c = 30 + 0.1*275

c = 30 + 27.5

c = $57.5

C. Substituting with c = 48:

48 = 30 + 0.1m

48 - 30 = 0.1m

18 = 0.1m

18/0.1 = m

180 miles = m
