Question

The cost of renting a car is $55/wk plus $0.15/mi traveled during that week. An equation to represent the cost would be

y = 55 + 0.15x,
where x is the number of miles traveled.

Suppose you have a maximum of $100 to spend for the car rental. What would be the maximum number of miles you could travel?

Answer 1

300 miles

Explanation:

100 - 55 =45

45/.15 =300

so x = 300
