The table compares the Fahrenheit temperature set on the thermostat
to the cost of electricity for a large
building. Using this data, determine
the cost if the thermostat is set to
80°F?

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right

the answer should be a. snail

i those same problems in math and dont know how to do them
