what's all this ratio stuff?
16% better mileage means the current value times 1.16
An advertisement for a steel-belted radial tire states that this tire delivers 16% better gas mileage. If the present gas mileage is 24.5 mpg, what mileage would you expect if you purchased these tires? Round your answer to the nearest tenth of a mile per gallon.
26.5/X = 12/100
26.5(100)= 2650
2650=12X
2650/12X
3.18mpg
