Question

ace car rental rents cars for x dollars per day plus y dollars for each mile driven carlos renteda car for a 4 days drove 100 miles and spent 120 dollars Vanessa rented a car for one day drove it 240 and spent 80 dollars

Answer 1

`T=xd+ym\\x(4)+y(100)=(120)\\x(1)+y(240)=(80)\\\\4x+960y=320\\4x+100y=120\\860y=200\\y=(200)/(860)\\y=(10)/(43)\\\\x+240((10)/(43))=80\\x+(2400)/(43)=(3440)/(43)\\x=(1040)/(43)`

x = 1040/43 = $24.19 per day.

y = 10/43 = $0.23 per mile.
