Question 4849
let x = the number of miles driven

safety rent-a-truck charges 41.95+.29x
City rental charges 38.95+.31x

we can set them equal to one another to determine the mileage that would make them cost the same price:
41.95+.29x=38.95+.31x
subtract.29x-38.95 from each side to get:
41.95-38.95=.02x
3=.02x

Divide both sides by .02
150=x

Check this by plugging it back into both equations:
41.95 + .29(150) = 85.45
38.95+.31(150)= 85.45

they equal one another, so the answer is 150 miles.
