Lizzy: One pair of pants requires 8.5 feet of fabric. Nguyen needs to make 7 pairs of pants for the wedding. He has 3.5 yards of fabric. How many feet of fabric does Nguyen still need for the pants?.
Me: Hmmm, let me think. I think this is the detailed solution:
Pants = 8.5 * 7 = 59.5 feet. 3.5 yards = 10.5 feet. 59.5 - 10.5 = 49. Nguyen still needs 49 feet of fabric. Final answer: 49.
