Final answer:
To calculate the cost of purchasing materials for a fence, convert the measurement from feet to yards and multiply by the cost per yard.
Step-by-step explanation:
To calculate the cost of purchasing materials for a fence, we first need to convert the measurement from feet to yards, since the price is given in yards.
Since 3 feet is equal to 1 yard, we divide the length of the fence in feet (64 feet) by 3 to get the length in yards: 64 feet ÷ 3 = 21.33 yards.
Now, we can multiply the length in yards by the cost per yard ($26.76) to calculate the total cost of purchasing the materials: 21.33 yards × $26.76 = $568.42. Therefore, it will cost approximately $568.42 to purchase the materials for the fence.
