​What is the cost for Amy to buy the carpet and have it installed in the room? Do NOT include tax

Answer 1

Part B: $544.5

Explanation:

PART B:

The area
`A` of the carpet is the product of its dimensions:

`A =22ft*9ft`

`A =198ft^2`.

The carpet costs $2.00 per
`ft^2`; therefore, the total cost
`C_b` of the carpet will be

`C_b = (2.00\$/ft^2)*198ft^2`

`C_b = \$396`.

Also, the installer charges $0.75 per
`ft^2` to install the carpet; therefore, the total cost
`C_i` of installation will be

`C_i = (\$0.75/ft^2)*198ft^2`

`C_i = \$148.5`.

Thus, the total amount
`C_(tot)` it will cost Amy to buy the carpet and have it installed will be

`C_(tot) = C_b+C_i`

`C_(tot) = \$396+\$148.5\\\\\boxed{C_(tot) = \$544.5}`
