Boston Athletic Supply (BAS) makes game jerseys for athletic teams. The B. W. Krause soccer club has offered to buy 110 jerseys for the teams in its leagu $15 per jersey. The team price for such jerseys normally is $21, a 75% markup over BAS's purchase price of $12 per jersey. BAS adds a name and number jersey at a variable cost of $1 per jersey. The annual fixed cost of equipment used in the printing process is $9,600, and other fixed costs allocated to jerseys $1,900. BAS makes about 2,300 jerseys per year, so the fixed cost is $5 per jersey. The equipment is used only for printing jerseys and stands idle 75% of the usable time. The manager of BAS turned down the offer, saying, "If we sell at $15 and our cost is $18, we lose money on each jersey we sell. We would like to help your le but we can't afford to lose money on the sale." Read the requirements. Requirement 1.
