Step-by-step 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.
