Question

The cost of a rug is given by the equation C=1.2A+60, where C is the cost in dollars and A is the area of the rug in square feet. what is the area in square feet, of a rug that costs $180?

Answer 1

C = 1.2A + 60

so

180 = 1.2A + 60

subtract 60 from each side

120 = 1.2A

divide both sides by 1.2

100 = A

The area of the rug is 100 square feet.

Answer 2

yeah what they said ^^

100 sq. feet
