Tina is approached by a local youth camp that would like to have 2,000 T-shirts produced.The camp asked Tina to produce the shirts for $9.00 each rather than the standard price of $10.00.Tina can produce up to 28,000 shirts a month,so the special order will not affect regular customer sales.Variable costs per unit will remain at $5.50,but production of the shirts will require a special machine that costs $2,500.This special order will have no other effect on monthly fixed costs.
(1)Using differential analysis,determine whether Tina would be better off accepting or rejecting the special order.
(2)Assume Tina can only produce 25,000 T-shirts per month,and that regular customer sales would decrease as a result of the special order.Using differential analysis,determine whether Tina would be better off accepting or rejecting the special order.
