Answer:
C)
In order to use the Cost-Benefit Principle correctly we need to compare the marginal benefit of the new spending, which is $25 million, with the marginal cost of the new spending, which is $50 million. This new spending makes no economic sense.
Step-by-step explanation:
The cost-benefit principle in accounting states that the additional benefit must outweigh additional cost in an accounting system.
Spending of $250 million is giving $400 million revenue. The new proposal of spending $300 million to get $425 million implies we are spending extra $50 million to make extra $25 million.
This is not a good investment according to the cost-benefit principle.
