Question

The total cost for carpet (y) is proportional to the number of square feet (x) purchased. The cost per square foot is $9. Which

equation could represent the total cost for 225 square feet of carpet?

Answer 1

225*9=y

Explanation:

Original equation would be x*9=y

You would replace x with 225 because it is the number of square feet.

The overall answer would be 225*9=2025 if you wanted the equation solved.

Answer 2

`y=9(225)=2025`

Explanation:

y represents the total cost for carpet.

x represents the number of square feet purchased.

So, the expression would be

`y=9x`

If we want to find the total cost for 225 square feet of carpet, we just need to replace this value for the x:

`y=9(225)=2025`

Therefore, the cost would be $2025 for 225 square feet of carpet.
