Question 13.

The estimated monthly cost of an energy-efficient refrigerator is $57, meaning the yearly cost is

$57\cdot12=\$684$

Question 14.

The least energy-efficient refrigerator costs $72 per month, meaning the annual cost is

$\$72\cdot12=\$864$

Therefore, the amount you will save on an energy-efficient refrigerator be

$\$864-\$684=\$180$

Hence, the amount saved on an energy-efficient refrigerator will be $180.
