Answer: she should get 30.45 miles per gallon with her new tyres.

Explanation:

After buying the Dunlop tires at a local Goodyear store, the salesperson told her that her mileage would increase by 5%.

If before this purchase, Maria was getting 29 mpg, it means that the amount by which her mileage will increase is

5/100 × 29 = 0.05 × 29 = 1.45 miles per gallon.

Therefore, the number of mileage that she should be getting with the new tires would be

29 + 1.45 = 30.45 miles per gallon.
