Answer:
$3.22 per square feet
Step-by-step explanation:
To solve, I usually set up an equation:
<u>sq ft</u> = <u>12 1/2</u> = <u> 1 </u>
$ 40.21 x
Then, use cross multiplication.
(12 1/2)x=40.21
Divide both sides by 12 1/2 or 12.5
x = 3.2168
Round to the hundredths place [because we're dealing with money]
$3.22
I hope this helps!
