Question

The cost of driving a car includes both fixed ans mileage costs. Assume that it costs $152.20 per month for insurance and car payments ans $0.22 per mile for gasoline oil and routine maintenance.
(a) Find value m and b so that y-mx=b modeks the monthly cost of driving the car x miles.
(b) What does the value of b represent.

Dr. Jane · Answer

.22 is a rate so that is our slope m 152.20 is your constant or fixed cost so that is b. Can you write the equation now?
