Final answer:
If the travel book line at Giada's Book Store were discontinued, the corporate profits for the current year would decrease by $58,000. This figure is obtained by subtracting the variable costs associated with the travel book line from its contribution margin.
Step-by-step explanation:
The question asks how corporate profits would have changed if the travel book line had been discontinued at Giada's Book Store. Evaluating the impact on corporate profits involves identifying the contribution margin that would be lost along with any variable costs that would also be eliminated if the travel book line were discontinued. The income statement shows a contribution margin of $97,000 for the travel book line, with additional order and delivery processing costs of $25,000, rent of $4,000, and allocated corporate costs of $10,000. To calculate the impact on corporate profits, we subtract the sum of these expenses from the contribution margin: $97,000 (contribution margin) - ($25,000 + $4,000 + $10,000) (variable expenses) = $58,000. Therefore, the decrease in corporate profits would be $58,000, which corresponds to option D.
