Question

A car rental costs $50 for the first day. Additional days cost $35 per day, unless the car is rented for 7 days or more, in which case there is a 10% discount on the daily rate.

Identify the expression which represents the cost of renting a car if the car has been rented for more than a week.
A) 45 + 35x
B) 45 + 31.5x
C) 50 + 35x
D) 50 + 31.5x​

Answer 1

The wording is unorthodox, but I believe the answer is D.

Answer 2

Answer: D) 50 + 31.5x

Explanation:

The expression for less than 7 days is 50 + 35x.

7 or more days has a 10% discount on the daily rate (35):

35 - 35(0.10) = 35 - 3.5 = 31.5

So, the new expression is: 50 + 31.5x
