Wanda plans to make a dress for the homecoming dance. The materials will cost the following amounts, sales tax included: pattern, $2.25; fabric, 5 1/2 yd at $3.57 per yd; thread, $0.60; interfacing, 3 7/8 yd at $1.35 per yd; and zipper, $1.69. Her friend saw the same dress in a store for $30, including sales tax. Would Wanda save more money making the dress by hand, buying it in the store, or would the costs be equivalent?
