Question

best rentals charges a daily fee plus a mileage fee for renting its cars. barney was charged $123 for 3 days and 300 miles, while Mary was charged $222 for 5 days and 600 miles. what does best rental charge per day and per mile?

Answer 1

3x + 300y = 123
and
5x + 600y = 222
With x being the day fee and y being our mileage fee.
You can solve this system whichever you you are most comfortable with,
but you should arrive at
\[x=24;\space\space y=\frac{17}{100}\approx0.17\]
So it's 24 dollars per day, and 0.17 dollars per mile.
