Suppose that you currently own a clothes dryer that costs $25 per month to operate a new efficient dryer costs $630 and has an estimated operating cost of $15 per month. how long will it take for the new dryer to pay for itself? months the clothes dryer will pay for itself in

Dryer will pay for itself in 63 months or 5 years and 3 months.

Step-by-step explanation:

Let after x months new dryer will pay for itself.

Old dryer is costing $25 to operate so after x months it will cost = 25x

Similarly new dryer which cost $630 and operating cost is $15 per month.

So after x months new drier will cost = $(630 + 15x)

If the new dryer pay for itself in x months then total cost of both the dryers after x months should be same.

Therefore, 25x = 630 + 15x

25x - 15x = 630

10x = 630

x =

x = 63 months

Or x = 5 years 3 months

Answer is 63 months or 5 years 3 months.
