suppose that you currently own a clothes dryer that costs $20 per month to operate. a new efficient dryer costs $305 and has an estimated operating cost of $15 per month. how long will it take for the new dryer to pay for itself? the clothes dryer will pay for itself in months.
Answer
# Explanation:
## Step1: Calculate monthly savings
The old - dryer costs $20 per month and the new one costs $15 per month. So the monthly savings is $20 - 15=5$ dollars.
## Step2: Calculate pay - back time
The new dryer costs $305. To find out how many months it takes to pay for itself, we divide the cost of the new dryer by the monthly savings. Let $n$ be the number of months. Then $n=\frac{305}{5}=61$.
# Answer:
61
