Answer:
The correct answer is $100,000.
Step-by-step explanation:
According to the scenario, the given data are as follows:
Contribution margin = $2,500 per hour
Extra time = 40 hours
Selling price = $100 per unit
So, we can calculate the increase in contribution margin by using following formula:
Increase in contribution margin = Contribution margin × Extra time
By putting the value in the formula, we get
= $2,500 × 40
= $100,000
