Riggs Company purchases sails and produces sailboats. It currently produces 1,270 sailboats per year, operating at normal capacity, which is about 80% of full capacity. Riggs purchases sails at $268 each, but the company is considering using the excess capacity to manufacture the sails instead. The manufacturing cost per sail would be $98 for direct materials, $86 for direct labor, and $90 for overhead. The $90 overhead is based on $78,740 of annual fixed overhead that is allocated using normal capacity. The president of Riggs has come to you for advice. It would cost me $274 to make the sails, she says, but only $268 to buy them. Should I continue buying them, or have I missed something?

Prepare a per unit analysis of the differential costs. (Enter negative amounts using either a negative sign preceding the number e.g. -45 or parentheses e.g. (45).)
