A car rental company charges $34 per day for a rented car and $0.50 for every mile driven. A second car rental company charges $
20 per day and $0.75 for every mile driven. What is the number of miles at which both companies charge the same amount for a one-day rental? A.
56 miles
First you want to make the equations for finding the total price of each rental car. We will say that x is the number of days and y is the number of miles. We will say the price for the first company is A = 34x + 0.50y and the second company is B = 20x + 0.75y. We want to find y where 34x+0.5y = 20x+0.75y and x=1. You should get 56 miles
