To calculate the price per inch of a 4-yard roll of plastic wrap that costs $2.88, we first need to convert yards to inches.
1 yard is equal to 36 inches. Therefore, 4 yards is:
\[
4 \text{ yards} \times 36 \text{ inches/yard} = 144 \text{ inches}
\]
Now, we divide the total cost by the total number of inches:
\[
\text{Price per inch} = \frac{\text{Total cost}}{\text{Total inches}} = \frac{2.88}{144}
\]
Calculating this gives:
\[
\text{Price per inch} = 0.02
\]
Thus, the price per inch is $0.02.
1 yard is equal to 36 inches. Therefore, 4 yards is:
\[
4 \text{ yards} \times 36 \text{ inches/yard} = 144 \text{ inches}
\]
Now, we divide the total cost by the total number of inches:
\[
\text{Price per inch} = \frac{\text{Total cost}}{\text{Total inches}} = \frac{2.88}{144}
\]
Calculating this gives:
\[
\text{Price per inch} = 0.02
\]
Thus, the price per inch is $0.02.
