Question 582944: You are trying to decide which of 2 cars to buy. An American made costs $14,500 and has a consumption of 28 miles/gallon. The other is Japanese, costs $21,700 and with a consumption of 19km/litre.
If the cost of petrol is $2.50 per gallon, estimate the number of miles you will need to drive the second car to compensate for the higher cost of the car.
You can put this solution on YOUR website! You are trying to decide which of 2 cars to buy.
An American made costs $14,500 and has a consumption of 28 miles/gallon.
The other is Japanese, costs $21,700 and with a consumption of 19km/litre.
If the cost of petrol is $2.50 per gallon, estimate the number of miles you will need to drive the second car to compensate for the higher cost of the car.
:
Change 19 km to mile
.6214(19) = 11.8066 mi/liter
Change to mi/gal
11.8066 * 3.785 = 44.688 = 44.7 mi/gal
:
Let m = no. of miles for the total cost of be the same
:
2.50* + 14500 = 2.50* + 21700
.0893m + 14500 = .0559m + 21700
.0893m - .0559m = 21700 - 14500
.0334m = 7200
m = 7200/.0334
m = 215,569 mi for the total cost of each to be about the same
:
:
See if that works out
Acost = 2.50* + 14500
cost = $33,747
:
Jcost = 2.50* + 21700
cost = $33.756
