One car rental agency rents a basic car at a daily rate of ​$37.95 plus 40 cents per mile. Another company rents a basic car for ​$42.95 plus 30 cents per mile. Find the mileage for which the cost is the same.

Respuesta :

Let x be the mileage that will cost the same

37.95 + 0.4x = 42.95 + .3x
0.4x - 0.3x = 42.95 - 37.95
0.1x = 3
x = 30
Ans: 30 miles
