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.

Explanation:
<em>The first step is to calculate amount of cash that would be charged</em>
<em>For 30 months, pay $520 per month for 30 months and an additional $10,000 at the end of 30 months.</em>
Present value is = 2,221
<em>Then</em>
<em>The present value of the payment options is =</em>
<em>($520 * PVA (24% 12,30) + $10,000 PV ( 24% 12,30))</em>
<em>$520 * 22.396 + $10,000 * 0.5521</em>
<em>$11646 + $ 5521</em>
<em>$17,167</em>
<em>Therefore the amount of cash the car dealer would charge is $17,167</em>
