A salesman rents a car for two trips from the same rental company. The rental company charges a daily fee plus a charge for each mile driven.
First trip, 2 days, 275 miles, cost $140.75
Second trip, 1 day, 95 miles, cost $59.75
How much did the rental company charge per day and per mile?
------------------------
2d + 275m = 140.75
d + 95m = 59.75
--------
Modify::
2d + 275m = 140.75
2d = 190m = 119.50
----
Subtract and solve for "m":
85m = 21.25
m = 25 cents (the per-mile rate)
-----
Solve for "d"::
d + 95m = 59.75
d + 95*0.25 = 49.75
d = $49.51 (daily rate)
