Answer:
If the marketing increase by $20,000; the net income will increase by $160.
Step-by-step explanation:
First, we need to calculate the current net income:
Net income= total contribution margin - fixed costs
Net income= 8,000*112 - 719,000
Net income= $177,000
Now, the net income with the changes incorporated:
New net income= 8,180*112 - (719,000 + 20,000)
New net income= $177,160
If the marketing increase by $20,000; the net income will increase by $160.
