Answer:
24 months
Step-by-step explanation:
The cost of installing insulation in a two bedroom home is $2,400
The monthly heating cost is $200, and it is then reduced by 50%
Then the new monthly heating cost can be calculated as follows
= 50/100 × 200
= 0.5 × 200
= $100
Therefore the number of months that it will take to recover the cost of insulation can be calculated as follows
= 2,400/100
= 24
Hence it will take 24 months
