Final answer:
To calculate the increase in NOI when sales increase to 1,001 units, we need to determine the contribution margin per unit and then calculate the difference in contribution margin between 1,001 units and 1,000 units. The contribution margin per unit is $28 and the increase in NOI would be $28.
Step-by-step explanation:
To calculate the increase in NOI when sales increase to 1,001 units, we need to determine the contribution margin per unit and then calculate the difference in contribution margin between 1,001 units and 1,000 units.
The contribution margin per unit can be calculated by subtracting the variable cost per unit from the selling price per unit. In this case, the selling price per unit is $80,000/1,000 units = $80, and the variable cost per unit is $52,000/1,000 units = $52. Therefore, the contribution margin per unit is $80 - $52 = $28.
The increase in NOI can be calculated by multiplying the increase in units (1,001 - 1,000 = 1) by the contribution margin per unit ($28). Therefore, the increase in NOI would be $28.
