Answer:
The company's income will decreases by $3,500 per year.
Step-by-step explanation:
Present Net Income :
 Service 1 = $45,000 
 Service 2 = ($1,500) 
 Total(old) = $45,000 + ($1,500) 
 = $43,500
 After closing of service 2 :
 Service 1 = $45,000 
 Company wide facility-level costs allocated to for service 2 = (5,000)
 Total(new) = Service 1 present income + Company wide facility-level costs
 = $45,000 + (5,000)
 = $40,000
Decrease in income = Total(old) - Total(new)
 = $43,500 - $40,000
 = $3,500
Therefore, the company's income will decrease by $3,500 per year.
