Average Costs per Mile Operating $0.28 $0.17 Total $1.02 $0 42 Car A $0.74 50 25 Car B If you drive 40,000 miles per year, by how much does the total annual expense for Car A exceed that of Car B over six years? The total annual expense for Car A exceeds that of Car B by $over sik years. (Round to the nearest dollar as needed)Explanation / Answer
Car A:
Average operating cost per mile = $0.28
Average Ownership cost per mile = $0.74
Total average cost per mile = $1.02
Annual average cost = Average cost per mile * miles driven in a year
= $1.02 * 40000 = $40800
Since the car is driven for 40000 miles each year, so for 6 years, the total expense will be:
6* $40800 = $244800
Car B:
Average operating cost per mile = $0.17
Average Ownership cost per mile = $0.25
Total average cost per mile = $0.42
Annual average cost per mile = Average cost per mile * miles driven in a year
= $0.42 * 40000 = $16800
Since the car is driven for 40000 miles each year, so for 6 years, the total expense will be:
6* $16800 = $100800
Now, over the 6 years, the total annual expense of car A exceeds that of car B by:
$244800 - $100800 = $144000
