Jack is currently driving into a headwind (17% decrease). if his normal mileage is 41 mpg, what will his car's mileage be in the headwind? round your answer to the tenths place

By the decrease of 17% in the mileage of Jack's car, the new mileage is only 83% of the previous mileage. To get the current mileage, we multiply the mileage by the percentage. That is,

new mileage = (41 mpg) (0.83)

= 34.03 mpg

Thus, the car's mileage in the headwind is only 34.03 mpg.
