## Elementary Algebra

We can use the following guideline to solve this problem, Current gas mileage + Increase = New gas mileage So, 24 + 18% $\times$ 24 = New gas mileage 24 + .18 $\times$ 24 = New gas mileage 24 + 4.32 = New gas mileage 28.32 = New gas mileage Hector should expect to get 28.32 miles per gallon.
