QUESTION 4 Talmont Products has dropped the price per unit of its smart phone product from $1,060 to $500. There are some units in work-in-process inventory that have costs of $600 per unit associated with them. Talmont could sell these units in their current state for $400. It will cost Talmont $40 to complete these units so that they can be sold for $500 each When the incremental revenues and costs are analyzed, the company is better off by: a. $500 per unit if they complete the units. Ob $40 per unit if they sell the units in their current state, Oc $200 per unit if they sell the units in their current state. $60 per unit if they complete the units. d. QUESTIONS The following monthly financial data is for Tina's T Shirt Company. The company makes 25,000 T-shirts each month. Total monthly data at Per unit 25,000 units Sales revenue $10.00 $250,000 Variable costs 5.50 137,500 Contribution margin $4.50 $ 112,500 Fixed costs 98,000 Profit $ 14,500 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
