If a wood floor costs $4.50 per square foot, how much is that per square yard?

Answer 1

Your answer would be 13.5 cause each yard is 3 feet

Answer 2

$0.50 is that per square yard

Explanation:

Unit rate is defined as the rate are expressed as a quantity as 1 such as 2 miles per hour or 5 km/hr.,

As per the statement:

If a wood floor costs $4.50 per square foot

⇒
`\text{Unit rate per square foot} = \$ 4.50`

We have to find how much is that per square yard

Use conversion:

1 square foot =
`(1)/(9)` square yards.

In 1 square foot = $ 4.50

then;

in 1 square yards =
`(1)/(9) \cdot 4.50 = \$0.50`

⇒
`\text{Unit rate per square yards} = \$0.50`

therefore, $0.50 is that per square yard
