- Q:What is the cost of 21 feet of wire for Andy? A:From the table given, we can see that 1 foot = 0.29 dollars. So, the cost of 21 feet of wire for Andy would be 21 * 0.29 = 6.09 dollars.
- Q:What is the cost of 14 yards of wire for Emily? A:We know that 1 yard = 3 feet. So, 14 yards = 14 * 3 = 42 feet. From the table given, we can see that 1 foot = 0.29 dollars. So, the cost of 42 feet of wire for Emily would be 42 * 0.29 = 12.18 dollars.
