Mark moved into a home with 1,200 square feet of living space with 8-foot-high ceilings throughout. The annual cost of heating and cooling the home is approximately $50 per 1,000 cubic feet of living space. Which value is the best estimate of Mark’s annual cost of heating and cooling the home?%0D%0A%0D%0A%09A.%09%0D%0A$60%0D%0A%0D%0A%09B.%09%0D%0A$192%0D%0A%0D%0A%09C.%09%0D%0A$333%0D%0A%0D%0A%09D.%09%0D%0A$480%0D%0A%0D%0A%09E.%09%0D%0A$3,000
B. $192
To calculate the cost, first find the volume of the living space by multiplying the square footage by the height of the ceilings:
1,200 sq ft * 8 ft = 9,600 cubic ft
Then, divide the volume by 1,000 cubic feet to find the number of units:
9,600 cubic ft / 1,000 cubic ft = 9.6
Finally, multiply the number of units by the cost per unit:
9.6 units * $50 = $480
Therefore, the best estimate of Mark's annual cost of heating and cooling the home is $480.
