Question

What were the rental rates?

Answer 1

answer/explanation:

• d = daily rental charge

• m = the charge per mile

Jon rented a car from a company that charged a daily rental fee and a mileage charge. He rented the car for 6 days and drove 300 miles and was charged $285.

1. 6d + 300m = 285

• His friend Amanda later rented the same car for 7 days and drove 260 miles and was charged $310.

1. 7d + 260m = 310

• by solving the system of equations

1. 6d + 300m = 285
2. 7d + 260m = 310

• we find

1. d = $35
2. m = $0.25

1. the daily rental charge is $35.

1. the company charge per mile is $0.25.

hope this helps
