Final answer:
The incremental profit from accepting the special order is -$3,000. Mohave should not accept the special order. If the special order was to purchase 2,000 umbrellas for $9.00 each, the incremental profit would be -$8,000. The special-order price per unit at which Mohave would be indifferent is $13.00.
Step-by-step explanation:
1. To compute the incremental profit from accepting the special order, we need to calculate the difference between the total cost of producing 1,500 umbrellas and the total revenues from selling them. The total cost for producing 1,500 umbrellas is $13.00 * 1,500 = $19,500. The total revenues from selling the umbrellas is $11.00 * 1,500 = $16,500. The incremental profit is the difference between the total revenues and the total cost, which is $16,500 - $19,500 = -$3,000.
2. Based on the incremental profit of -$3,000, Mohave should not accept the special order because it would result in a loss.
3. If the special order was to purchase 2,000 umbrellas for $9.00 each, the total cost for producing 2,000 umbrellas would be $13.00 * 2,000 = $26,000. The total revenues from selling the umbrellas would be $9.00 * 2,000 = $18,000. The incremental profit would be $18,000 - $26,000 = -$8,000.
4. If Mohave is operating at full capacity, the special-order price per unit at which Mohave would be indifferent between accepting or rejecting the special order would be the total cost per unit for producing 1 umbrella. The total cost per unit is $13.00/1 = $13.00.
