Answer 1

Answer:the approximate total cost of the cars sold in the U.S. during 2014 is 5 × 10^11 dollars.

Explanation:

The average cost of a new car in the United States was 3.2×10^4 dollars in 2014.

During 2014, about 1.6×10^7 new cars were sold in the U.S. Therefore, the total cost of the cars sold in the U.S. during 2014 would be

3.2×10^4 × 1.6×10^7

= 5.12 × 10^(4 + 7) = 5.12 × 10^11 dollars. Approximating the total cost of cars, it would be 5 × 10^11 dollars.
