Question 676091: James Millhouse is renting a car at a local rental agency. The cost of renting the car is $38 per day, plus $0.35 for each mile driven over 150 miles. James rented this car for one day and drove it over 150 miles.
a. What equation can be used to determine y, the total cost of the rental, if it is driven y miles?
b. James drove from Las Vegas to the south rim of the Grand Canyon, a distance of 280 miles. He then drove back to Las Vegas the same day along the same route to turn in his rental car. How much was the bill for his rental car?
c. If James only had $150 to spend on the rental car, how many miles could he drive?

You can put this solution on YOUR website!
y = .35m + 38
where m is miles over 150
...
2(280)-150 = 560 - 150 = 410
y = .35(410) + 38
y = 143.5 + 38
y = 181.5 the cost for the trip to the Grand Canyon and back
...
150 = .35m + 38
150 - 38 = .35m
112 = .35m

m = 320 miles for $150
