Please consider the complete question.
Michelle bought the same fabric on 3 different occasions and recorded the data below.
Yards of Fabric Total Cost
2.2 $2.53
3.6 $4.14
4.2 $4.83
What was the price per yard of fabric?
To find the cost per yard of fabric, we will divide cost of yards by number of yards.
[tex]\text{Cost per yard}=\frac{\text{Cost}}{\text{Number of yards}}[/tex]
[tex]\text{Cost per yard}=\frac{\$2.53}{2.2\text{ yards}}[/tex]
[tex]\text{Cost per yard}=\frac{\$1.15}{\text{ yard}}[/tex]
Let us find cost per yard using 2nd set of data.
[tex]\text{Cost per yard}=\frac{\$4.14}{3.6\text{ yards}}[/tex]
[tex]\text{Cost per yard}=\frac{\$1.15}{\text{ yard}}[/tex]
Similarly we will find cost per yard for 3rd set of data.
[tex]\text{Cost per yard}=\frac{\$4.83}{4.2\text{ yards}}[/tex]
[tex]\text{Cost per yard}=\frac{\$1.15}{\text{ yard}}[/tex]
Therefore, the cost per yard of fabric is $1.15.
