Answer 1

22 x 15% = 3.3 + 22 = 25.3 mpg

Answer 2

Increase in mileage of the car will be = 3.3 miles per gallon.

Explanation:

Mudrik installed a device on his car that guarantees the increase in mileage by 15%.

Current mileage of the car is = 22 miles per gallon.

then the expression representing mileage of the car will be mileage =

(22 + 15% of 22)

therefore, increased mileage of the car will be = 22 + 3.3 = 25.3 miles per gallon

So increase in mileage will be = 25.3 - 22 = 3.3 miles per gallon.
