Cheap Car Rental rents a car at $50 per day plus $0.55 per mile. Best Car Rental charges $55 per day plus $0.50 per mile. In how many miles, m, will both cars cost the same?

100 miles

Step-by-step explanation:

y=.55m+50 equation 1

y=.50m+55 equation 2

.55m+50=.50m+55 substitute value of y in equation 1 into equation 2

.05m=5

m=100

check answer by substituting 100 into both equations.

Y=.55(100)+50

y=55+50

y=105

y=.50m+55

y=.50(100)+55

y=50+55

y=105

each side has a different length.
