Question

When Sal rented a car for 3 days, he drove it a total of 90 miles and paid $193.35. When Ashley rented a car for 5 days and drove it a total of 125 miles, she paid $318.50. If the car rental company charges a fee per day and a rate per mile, what is the fee per day to rent a car?

Answer 1

lets assume that fee per day is x dollars and rent per mile is y dollars

according to given theory
equations will be

3x+90y = 193.35

and

5x+125y = 318.50

now solve for x and y
x is the required answer for the given problem
