Question

Cellulon, a manufacturer of home insulation, wants to develop guidelines for builders and consumers on how the thickness of the insulation in the attic of a home and the outdoor temperature affect natural gas consumption. In the laboratory, it varied the insulation thickness and temperature. A few of the findings are:

How much natural gas can homeowners expect to use per month if they install 6 inches of insulation and the outdoor temperature is 40 degrees F? (Round your answer to 2 decimal places.)

What effect would installing 7 inches of insulation instead of 6 have on the monthly natural gas consumption (assuming the outdoor temperature remains at 40 degrees F)? (Round your answers to 2 decimal places.)

  (Click to select)YesNo , logically, as the amount of insulation (Click to select)decreasesincreases and
  outdoor temperature (Click to select)increasesdecreases, the consumption of natural gas decreases.

Explanation / Answer

a) Expect to use per month=56.26-0.4*6-0.59*40 =30.26

b) )decrease  of cubic feet of monthly natural gas consumption,
down to 0.4 cubic feet

c) Yes as the amount of insulation sincreases and outdoor temperature increases  the consumption of natural gas decreases
