Problem
QUESTION 6 Solve the problem. The normal gasoline mileage of a car is \( 44 \mathrm{mpg} \). On a smooth road, its mileage is \( 12 \% \) higher. What is its mileage on a smooth road? Round your answer to the nearest tenth. \( 50 \mathrm{mpg} \) \( 5.3 \mathrm{mpg} \) \( 49.3 \mathrm{mpg} \) \( 44 \mathrm{mpg} \)
Solution
Step 1 ：\(mileage = (1 + 0.12)(44 \mathrm{mpg})\)
Step 2 ：\(mileage = (1.12)(44 \mathrm{mpg})\)
Step 3 ：\(mileage = 49.28 \mathrm{mpg}\)
