Question

Suppose Rent-A-Truck s rates are $50 a day plus $0.50 per mile and Sam s U-Drive s are $70 a day plus $0.45 a mile.

At what mileage would the cost for both be the same?

anonymous · Answer

Rent a truck : 50 + .50m
Sams u drive : 70 + .45m

at what mileage are they equal....
50 + .50m = 70 + .45m

now just solve for m.....can you do that ?

anonymous · Answer

so are you just subtracting from both sides & dividing ?

anonymous · Answer

well...yes...kinda....what you subtract from one side, you add to the other. And at the end you will have to divide

anonymous · Answer

5m=20
m=4

anonymous · Answer

50 + .50m = 70 + .45m
.50m - .45m = 70 - 50
.05m = 20
m = 20/.05
m = 400

do not forget the decimals
