Answer:
Net operating income $8,950
Step-by-step explanation:
The overall impact on the net operating income is the amount of increase in contribution from the addtional sales less the increase in monthly advertising budget.
$
Contribution = ($75 × 190) = 14,250
Fixed cost - advertising ( 5,300)
Net operating income 8950
Please, note that the fixed costs of $194,000 per month are not relevant for this decision. Simply because they would be incurred either way and that are not completely traceable to the increase sales.
