Please help!! It's due on Friday... Maria’s current car gets 24 miles per gallon. Last year she drove 15,000 miles. Last year gas cost an average of $1.35.

a. How much did Maria spend for gas for her car last year?

b. Maria is buying a new car that is more gas‐efficient and should average 32 miles
per gallon. If she drives the car 15,000 miles in the next year and gas costs an
average of $1.35, how much will she spend for gas in the next year?

c. How much money will Maria save in gas costs in the next year by driving her new
car as opposed to her old one?

d. What percent decrease in gas costs for one year will Maria realize by driving her
new car?
