Ex: Linear Equation Application (Cost of a Rental Car)

This video provides an example of how to determine how far you can drive a rental car with a specific amount of money to cover the fixed cost and mileage cost.

Yes, you are correct, but part of understanding math is to be able to write equations to represent situations. This is why I went through this process. Thank you for the comment and for watching.

Thank you so much. This is the right way to understand the subject.

A car-leasing agency purchases new cars each year for use in the agency. The
cars cost $15, 000 new. They are used for three years, after which they are sold for $3, 600.

The owner of the agency estimates that the variable costs of operating the cars, exclusive of gasoline, are $0.16 per mile. Cars are leased at a flat rate of $0.33 per mile (gasoline not
included).

a) What is the break-even mileage for the three-year period?

b) What are total revenue, total cost, and total profit for the three-year period if a car is
leased for 50, 000 miles?

c) What price per mile must be charged in order to break even if a car is leased for 50, 000
milcs over a period of three years?

d) What price per mile must be charged in order to earn a profit of $5, 000 per car over its
three-year lifetime if it is leased for a total of 50, 000 miles?
How can I solve it

haha, , interesting but there is much much simpler way...

u know u got $336, and want to know no. of miles that can be driven in a week...
hence 336-210 = 126
now cost of one mile = .15 so 126/0.15 = 840...
Why complicate math further brother ? it is already so complicated lol..
