Martin Corporation, the maker of a variety of rubber products, is in the midst of a business downturn and has many idle facilities. Nationwide Tire Company has approached Martin to produce 300,000 oversized tire tubes for $2.40 each. Martin predicts that its variable costs will be $2.60 each. Its fixed costs, which had been averaging $2.00 per unit on a variety of products, will now be spread over twice as much volume. The president commented, "Sure we will lose $.20 each on the variable costs, but we will gain $1 per unit by spreading our fixed costs over more units. Therefore, we should take the offer because it would gain us $.80 per unit." Martin currently has a volume of 300,000 units, sales of $1,200,000, variable costs of $780,000, and fixed costs of $600,000. Required: a.
