Answer:
There are 3 feet in a yard, so a 2-yard piece of aluminum wire is 6 feet long.
To find the price per foot, we can divide the total cost by the total length:
Price per foot = Total cost / Total length
Price per foot = $15.96 / 6 feet
Price per foot ≈ $2.66
Therefore, the price per foot of the aluminum wire is approximately $2.66.
