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?
Pants = 8.5 * 7 = <<8.5*7=59.5>>59.5 feet
3.5 yards = 10.5 feet
59.5 - 10.5 = <<59.5-10.5=49>>49
Nguyen still needs 49 feet of fabric.
