Problema Solution

joe rented car for 6 days and drove 300 miles charged $195. his friend rented same car for 5 days and drove 240 miles was charged $161. what was daily rental charge? how much did company charge per mile?

Answer provided by our tutors

let it be x and y

6x+300y=195 and 5x+240y=161

solving both equations we get

2y=(195/6)-(161/5)

=>2y=32.5-32.2

=>2y=0.30

=>y=0.15 = charge per mile

now charge for day=(195-300*(0.15))/6=(195-45)/6=(150)/6=25
