How many feet of fabric does Nguyen need for the pairs of pants? ** Pants = 8.5 * 7 = <<8.5*7=59.5>>59.5 feet
How many feet of fabric does Nguyen have? ** 3.5 yards = 10.5 feet
How many feet of fabric does Nguyen still need? ** 59.5 - 10.5 = <<59.5-10.5=49>>49
How many feet of fabric does Nguyen still need? ** Nguyen still needs 49 feet of fabric.
