Final answer:
The man should seek a payment size of approximately $239.67.
Step-by-step explanation:
To calculate the size of payment the man should seek, we can use the formula for the future value of an annuity:
FV = P * ((1 + r)^n - 1) / r
Where FV is the future value, P is the payment amount, r is the interest rate per period (in this case, 6% divided by 12), and n is the number of periods (in this case, 5 years multiplied by 12).
Plugging in the given values, we have:
FV = 1600 * ((1 + 0.06/12)^(5*12) - 1) / (0.06/12)
Solving the equation results in:
FV = 1600 * (1.005)^60 * 239.6657
Therefore, the man should seek a payment size of approximately $239.67.
