Question

Suppose that two certain cars have the following average operating and ownership cosis. If you drive 30,000 miles per year, by how much does the total annual expense for Car A exceed that of Car B over four years? The total annual expense for Car A exceeds that of Car B by $ over four years. (Round to the nearest dollar as needed.

Answer 1

To find the difference in total annual expenses for Car A and Car B over four years, calculate the average cost per year for each car, multiply it by 4, and subtract the total expense of Car B from Car A. Using the given average costs per mile, the total annual expense for Car A exceeds that of Car B by $200 over the four years.

Step-by-step explanation:

To find the difference in total annual expenses for Car A and Car B over four years, we need to calculate the total expense for each car and then subtract the total expense of Car B from Car A. Here's how:

1. Calculate the average operating and ownership cost per year for each car by multiplying the average operating and ownership cost per mile by 30,000 miles.
2. Multiply the average cost per year by 4 to get the total expense over four years for each car.
3. Subtract the total expense of Car B from Car A to find the difference.

Let's suppose the average operating and ownership cost per mile for Car A is $0.15 and for Car B is $0.10. Then, the total annual expense for Car A would be $150 (0.15 * 30,000) and for Car B would be $100 (0.10 * 30,000). Multiplying these by 4 gives us a total expense over four years of $600 for Car A and $400 for Car B. Therefore, the total annual expense for Car A exceeds that of Car B by $200 over the four years.
