For what mileage is the cost the same?
Sunset rents an SUV at $21.95 plus $0.23 per mile. Sunrise rents the same vehicle for $24.95 plus $0.19 per mile. For what mileage is the cost the same?
use m for miles and c for cost
write one equation for each rental company
Sunset= 21.95 + 0.23m= cost
Sunrise= 24.95 + 0.19m= cost
21.95 + 0.23m = 24.95 + 0.19m
0.23m - 0.19m = 24.95 - 21.95
0.04m = 3.00
m=3/ 0.04
m=75 miles = for what milage is the cost the same
check
Sunset= 21.95 + 0.23m= 21.95 + 0.23(75) = $39.20
Sunrise= 24.95 + 0.19m= 24.95 + 0.19(75)=$39.20
