Final answer:
The differential revenue from the offer for Jacoby Company is $450,000, which is derived by multiplying 30,000 units by the offered price of $15 per unit. The correct option is (d).
Step-by-step explanation:
The differential revenue from accepting the offer from an exporter for Jacoby Company is calculated by subtracting the domestic sales revenue from the revenue generated from the exporter's offer.
Since the offer will not affect normal production or domestic sales prices, we calculate the differential revenue as follows: 30,000 units times $15 per unit equals $450,000. Therefore, the acceptance of the offer will generate $450,000 in differential revenue, which corresponds to option d in the multiple-choice question provided.
