Question

Maria Fay bought four Dunlop tires at a local Goodyear store. The salesperson told her that her mileage would increase by 8%. Before this purchase, Maria was getting 24 mpg. What should her mileage be with the new tires? (Round to the nearest hundredth.)

Answer 1

We know that

• Maria was getting 24 mpg (miles per gallon).

,

• Her mileage would increase by 8% with the new tires.

First, we find 8% of 24 mpg, remember that 0.08 is equivalent to 8%.

`0.08\cdot24=1.92`

Second, add the 8% calculated to the mileage.

`24+1.92=25.92`

Therefore, her new mileage is 25.92 mpg.
