As a result of increased sales, Media Box needs 420,000 jewel-case liners rather than 270,000. Media Box has enough existing capacity to make all of the liners it needs. In addition, due to volume discounts, its variable costs of making each liner will decline to $0.26 per liner. Assume that by outsourcing, Media Box can reduce its current fixed costs ($48,600) by $9,500. There is no alternative use for the factory space freed through outsourcing, so it will just remain idle.
