Question

I need help with this word problem.

Answer 1

$3.22 per square feet

Explanation:

To solve, I usually set up an equation:

sq ft = 12 1/2 = 1

$ 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!

Answer 2

3.22 per sq ft

Explanation:

Take the total cost and divide by the amount of tiles

40.21 / 12.5

3.2168 per sq ft

Rounding to the nearest cent

3.22 per sq ft
