Answer:
B : $6.85
Step-by-step explanation:
Because Dora, Inc. has enough capacity to fill the special order in excess of regular sales volume, the fixed cost of its remain unchanged at $196,000.
Widget variable cost per unit of Dora is 210,000/70,000 = $3
To break even on the special order, the respective total sales amount has to cover all related cost, including allocated fixed cost, variable cost as well as additional shipping charges. Putting all the numbers together, we have:
3,000 x P - 196,000 x (3,000/73,000) - 3 x 3,000 - 3,150 = 0 with P is the selling price.
Solve the equation we get P = 6.73. Option answer A,C or D will result in loss for this special order. So, the suitable answer is B.
