This "it" thing had a "brief" existence of just 16 months. The way it's referred to, it seems 16 months is not a long time for this to exist. Something much bigger, the transcontinental telegraph, came along. 
So "supplant" seems to mean "to replace, supersede, or surpass".

Answer:
Effect on net income=$328.22
Explanation:
DSO Formula is:
DSO=(Account Receivable/Credit sales)x365
Current DSO is: 
DSO=(11500/100000)x365
DSO=41.975 days
In order to calculate the amount lowered we replace Account Receivable in DSO formula by X. DSO is 27 days
27=(X/100000)x365
X=$7397.26
Now:
Decrease in Account Receivable =$11500 - $7397.26=$4102.74
Effect on net income=$4102.74 * 8%
Effect on net income=$328.22
