Required:

a-1.

A large discount store has approached the owner of Lang about buying 5,000 calculators. It would replace The Math Machines label with its own logo to avoid affecting Langs existing customers. Because the offer was made directly to the owner, no sales commissions on the transaction would be involved, but the discount store is willing to pay only $5.50 per calculator. Calculate the contribution margin from the special order. (Negative amount should be indicated by a minus sign.)

a-2.

Should Lang accept the special order?

	Yes
	No

Lang has an opportunity to buy the 40,000 calculators it currently makes from a reliable competing manufacturer for $5.60 each. The product meets Langs quality standards. Lang could continue to use its own logo, advertising program, and sales force to distribute the products. Should Lang buy the calculators or continue to make them?
