Refer to the data for Problem 13-43. Assume the fabric costs $4.40 per yard in 2020 and $4.55 per yard in 2019.

Data From Problem 13-43

Goldstein Company manufactures wallets from fabric. In 2019, Goldstein made 2,700,000 wallets using 1,875,000 yards of fabric. In 2019, Goldstein has capacity to make 3,600,000 wallets and incurs a cost of $10,800,000 for this capacity. In 2020, Goldstein plans to make 3,348,000 wallets, make fabric use more efficient, and reduce capacity. Suppose that in 2020 Goldstein makes 3,348,000 wallets, uses 2,160,000 yards of fabric, and reduces capacity to 3,100,000 wallets at a cost of $10,540,000.
