Question 15813: ok i have to define a variable and write an equation to model the situation.then solve...here is the problem:
TRUCK RENTAL:the rate to rent a certain truck is $55 per day and 20cents per mile. your family pays $80 to rent this truck for one day. how many miles did your family drive?

You can put this solution on YOUR website!
Let x = number of miles driven at .20 cents per mile,
Truck rental is for 1 day for a total of $80.00

Total cost of rental:
55 + .2x = 80

Subtract 55 from each side:
55-55 + .2x = 80-55
.2x = 25

Divide both sides by .2
%28.2x%29%2F.2+=+25%2F.2
x=+250%2F2=+125+ miles
