Answer:
If the company decides to increase its advertising budget, its net profits will  decrease by $200 (= $56,800 - $57,000). 
Explanation:
The company is currently selling 5,000 units per month at $150 per unit, and its total variable costs are $90 per unit. 
Fixed expenses are $243,000 per month. 
Current income statement:
sales revenue =                    $750,000
minus variable costs =         ($450,000)
<u>minus fixed costs =              ($243,000)  </u> 
net income =                           $57,000
If the company increases its advertising budget be $11,000 it should sell 180 more units per month, the new income statement would be:
sales revenue =                    $777,000
minus variable costs =         ($466,200)
<u>minus fixed costs =              ($254,000)  </u> 
net income =                           $56,800
If the company decides to increase its advertising budget, its net profits will  decrease by $200 (= $56,800 - $57,000).
