Solution :
Given :
The bonds offer a 
of 4.5% per year
Tax rate = 10% = 0.10
Inflation rate = 2
= + 
= 2 + 4.5
= 6.5
= 
= 
= 5.85
After tax real interest rate = 
-
= 5.85 - 2.0
= 3.85
= 7.0
= +
= 7 + 4.5
= 11.5
= 
= 10.35
= 11.5 x (1 - 0.10)
= 11.5 x 0.90
= 10.35
= -
= 10.35 - 7.0
= 3.35
Putting all the value in table :
Real interest Nominal interest After tax nominal After tax
rate rate interest rate interest rate
2.0 4.5 6.5 5.85 3.85
7.0 4.5 11.5 10.35 3.35
Comparing with the 
, a 
will increase the after after tax real interest rate when the government taxes nominal interest income. This tends to encourage saving, thereby increase the quantity of investment in the economy and the increase the economy's long-run growth rate.

Answer:
$72,600
Explanation:
Ending balance of the account receivable can be calculated by adding credit sales in beginning balance and deducting any account receivable written-off.
As we have the ending balance of account receivable, we need to calculate credit sales by following formula:
Account receivable Ending Balance = Account receivable Beginning Balance + Credit Sales - Bad Debt - Ending Balance
$320,000 = $260,000 + Credit Sales - $12,600
$320,000 = $247,400 + Credit Sales
Credit Sales = $320,000 - $247,400 = $72,600
