Answer:
$3,756.77
Step-by-step explanation:
The computation of the annual net savings from installing this system is shown below
Given that 
Reduction in average mail time= 1.5 days 
 And, Reduction in clearing and processing time = 1day 
 So, Total reduction = 1.5 + 1 = 2.5 days 
 No. of checks per day= 198 
 Average Value= $2300 
 So, the Value of all checks per day is 
= 2300 × 198
= $455,400 
 Now total savings is 
= $455,400 × 2.5 days × 0.00011 × 365 days
= $45,710.77 
 The Cost of service is 
= Annual fee + variable fee
= $27,500 + 0.20 × 198 × 365
= $41,954 
 Now 
finally Net savings is 
= $45,710.77 - $41,954
= $3,756.77
