Question 1187382: The cost of renting a car is $40/week plus $0.25/mile traveled during that week. An equation to represent the cost would be y=40+0.25x, where x is the number of miles traveled.
a. What is your cost if you travel 56 miles?
b. If your cost was $59.75, how many miles were you charged for traveling?
Suppose you have a maximum of $100 to spend for the car rental. What would be the maximum number of miles you could travel?

56 miles*$0.25/mile =$14
so y(56)=$40+$14=$54.
-
59.75=40+0.25x
19.75=0.25 x
x=79 miles
-
100=40+0.25x
$60=$0.25x/mile
x=240 miles
