Answer:
It will take 83 days to recover the extra cost
Step-by-step explanation:
To determine the length of time it will take to recover the extra cost, it will be logical that we compare the $200 extra cost to the total savings in running cost made for a year and covert this into days
The total savings in running cost is the cost savings per hour multiplied by the number of hours in a year.
The calculations are set below:
Savings in running cost per hour = $0.1
Total savings in a year = 365 days × $0.1 × 24 = $876
Extra cost of Energy Star refrigerator = $200
If total savings for a year is $876 , then equivalent length of time to save $200 would be
Length of time = 200/876 × 365 days = 83 days
It will take 83 days to recover the extra cost
