Final answer:
To find the price per foot of a 6-yard aluminum wire that costs $3.96, you convert yards to feet (18 feet in 6 yards) and divide the total price by the length ($3.96 ÷ 18 feet), resulting in $0.22 per foot.
Step-by-step explanation:
To find the price per foot for the aluminum wire, we must first convert the length of the wire from yards to feet. There are 3 feet in a yard, so a 6-yard long wire is equivalent to 6 yards × 3 feet/yard = 18 feet long.
Next, we divide the total cost of the wire by the total length in feet to find the price per foot.
Total cost: $3.96
Total length: 18 feet
Price per foot: $3.96 ÷ 18 feet = $0.22 per foot
Therefore, the price per foot of the aluminum wire is $0.22.
