The student's question asks for determining the equal annual withdrawals from an account with $100,000 initial investment at 20% interest rate over 8 years that would deplete the account. By using the annuity payout formula, the calculations show that the correct withdrawal amount is approximately $31,030 per year, which makes option C the correct answer.

The question involves calculating the equal withdrawals from an investment account over a period of 8 years based on an initial investment and a fixed interest rate.

To find the equal annual withdrawals that would deplete the account at the end of 8 years, we need to use the formula for the annuity payout.

This formula is based on the present value of an annuity formula:

PV = PMT ×
((1 - (1 + r)^(-n)) / r)

Where:

PV = Present Value of the annuity (the amount initially invested),

PMT = Periodic payment (annual withdrawal in this case),

r = Interest rate per period,

n = Number of periods.

For this question:

PV = $100,000,

r = 20% or 0.20,

n = 8.

To find PMT, we rearrange the formula:

PMT = PV /
((1 - (1 + r)^(-n)) / r)

Substitute the given values:

PMT = $100,000 / ((1 - (1 + 0.20)^{-8}) / 0.20)

Solving this, we find:

PMT = $100,000 / ((1 -
(1 + 0.20)^(-8)) / 0.20) = $31030 (approximately)

The correct answer is C. $31030.

The withdrawals of approximately $31,030 per year will deplete the account entirely at the end of 8 years.
