Answer and Explanation:
The computation is shown below:
a. The Accumulated amount of her investment atter taxes is
Before that first we have to determine the future value which is shown below:
As we know that
Future value = Present value × (1 + interest rate)^number of years
= $29,000 × (1 + 0.04)^11
= $44,644.17
And, the tax rate is 15%
So, the after tax value is
= $44,644.17 × (1 - 0.15)
= $37,947.54
b. Now for the second part it is
= Annual cash flows × Annuity factor at 3.4% for 11 years
= $29,000 × 10.638
= $308,502
