Question

can someone help me solve this one.

Best Rentals charges a daily fee plus a mileage fee for renting its cars. Barney was charged $123.00 for 3 days and 300 miles, while Mary was charged $216.00 for 5 days and 600 miles. What does Best Rental charge per day, for mileage?

Answer 1

put
\[x=\text{ price per day}\]
\[y=\text{ mileage fee}\] then you get two equations
\[3x+300y=123\] and
\[5x+600y=216\] and now solve for x and y

Answer 2

BarneyFee = $123 = 3*DayFee + 300*miles*milageFee
MaryFee = $216 = 5*DayFee + 600*miles*milageFee

Answer 3

i like touchymath way. but you still have to solve

Answer 4

i would multiply
\[3x+300y=123\] by -2 to get
\[-6x-600y=-246\] then add to
\[5x+600y=216\] to get
\[-x=-30\] or
\[x=30\]so $30 per day

Answer 5

The steps to the solution are in the attached file
DayFee = $30/day
MileFee = $0.11/mile
