Question

Maria Fay bought four Dunlop tires at a local Goodyear store. The salesperson told her that her mileage would increase by 4%. Before this purchase, Maria was getting 22 mpg. What should her mileage be with the new tires? (Round to the nearest hundredth.)

Answer 1

Answer:

22.88 mpg

Step-by-step explanation:

An increase of 4% can be represented as (100% + 4%). Think of it as you're getting 100% and an additional 4%.

Now multiple your original mileage by the increase:

22(100% + 4%)

=22(1.00 + .04)

=22(1.04)

=22.88
