Explanation:
The computation is as follows
a. Total withdrawn amount
= Principal amount + total interest earned
where,
Principal amount = $40,600
And, the total interest earned is
= $40,600 × 10% × 10 years
= $40,600
So, the total withdrawn amount is
= $40,600 + $40,600
= $81,200
b. Now total withdrawn amount in case of compounded annually
= Principal amount × (1 + interest rate)^number of years
= $40,600 × (1 + 0.10)^10
= $40,600 × 2.5937424601
= $105,305.94
c. Now total withdrawn amount in case of compounded semi annually
= Principal amount × (1 + interest rate)^number of years
= $40,600 × (1 + 0.05)^20
= $40,600 × 2.6532977051
= $107,723.89
