Answer:
$0.50 is that per square yard
Step-by-step 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
⇒[tex]\text{Unit rate per square foot} = \$ 4.50[/tex]
We have to find how much is that per square yard
Use conversion:
1 square foot = [tex]\frac{1}{9}[/tex] square yards.
In 1 square foot = $ 4.50
then;
in 1 square yards = [tex]\frac{1}{9} \cdot 4.50 = \$0.50[/tex]
⇒[tex]\text{Unit rate per square yards} = \$0.50[/tex]
therefore, $0.50 is that per square yard
