samantha is buying carpet for her bedroom floor, which is a 15-foot-by-12-foot rectangle. if carpeting cost $1.2 per square fot, how much will it cost samantha to carpet her bedroom?
cost= area*cost/area= 15*12*1.20

Multiply: 15 * 12 * 1.20 = ?
in my books theres A.$68 B.$144 C.$180
Either you've copied the problem wrong or the answer key is wrong.
The area of the carpet is 180 square feet. At $1.20 per square foot, it will cost her $216.
