5) It cost Casey $415.50 for new carpet in her bedroom. If the room is 12.5 feet wide and 15 feet
long, what was the cost per squre foot?

2.216

I'm not sure how you need to round it, but here are two ways:

$2.22 (nearest hundredth)

$2.21 (nearest tenth)

Step-by-step explanation:

We need to find the total amount of square feet and then divide the cost of the carpet by the square feet we find.

So, first we can multiply 12.5 by 15 because that will give us the area, which is measured in square feet. Area is always measured in square units. That leaves us with 187.5 square feet.

Next, we need to divide the total cost of carpet by the amount of square feet. Do this:

415.5 ÷ 187.5

When you solve this, you get 2.216, but money normally has only 2 decimal places. We will probably need to round this, unless the problem states otherwise.

So, if we round to the nearest hundredths, we get $2.22 per square foot.

If we round to the nearest tenths, we get $2.21 per square foot.
