An owner finds that when he uses a clamshell luggage carrier on top of his car, it cuts his gas mileage by 3.1%. If he normally gets 40 mpg, what is his mileage when he uses the carrier?

a) 38.7 mpg
b) 38.8 mpg
c) 38.9 mpg
d) 39.0 mpg

To calculate the car's mileage with the clamshell carrier, take 3.1% of the original 40mpg, which is 1.24mpg, and subtract it from the original mileage, resulting in 38.76mpg. After rounding to the nearest tenth, the mileage with the carrier is 38.8mpg. The correct option is (b) 38.8 mpg .

Explanation:

The student is asking about the effect of using a clamshell luggage carrier on top of a car and how it impacts the car's gas mileage. If the car usually gets 40 miles per gallon (mpg), and using the carrier reduces the mileage by 3.1%, we can calculate the new mileage by finding 3.1% of 40mpg and then subtracting this value from the original mileage.

To calculate 3.1% of 40mpg:
(3.1 / 100) imes 40mpg = 1.24mpg

Subtracting this from the original mileage gives us the new mileage:
40mpg - 1.24mpg = 38.76mpg

Since we only have choices that are rounded to the nearest tenth, the closest answer to 38.76 is 38.8mpg, which is option 38.8 mpg.
