The present value of Peregrine's endowment can be calculated by adding the present value of his earnings to his current consumption. His current consumption is $1, and his future earnings are $1,680. To find the present value of the future earnings, we discount them by the interest rate of 20% (or 0.2). The formula for the present value (PV) is PV = FV / (1 + r)^n, where FV is the future value, r is the interest rate, and n is the number of periods. Here, FV = $1,680, r = 0.2, and n = 1 (since the earnings are one period in the future). So, PV = $1,680 / (1 + 0.2) = $1,680 / 1.2 = $1,400. Adding his current consumption of $1 gives a total of $1,400 + $1 = $1,401. However, this calculation does not match any of the provided options, indicating a misunderstanding in the initial calculation approach. Correctly, the present value of his endowment should consider both his current consumption and his future earnings, properly discounted. The correct calculation should sum his current assets and the present value of his future earnings. Given the discrepancy in the initial explanation, let's correct the approach:Peregrine's endowment includes his current consumption and his future earnings. The correct calculation for the present value of his endowment, considering an interest rate of 20%, should properly account for all components of his endowment (current assets/consumption and future earnings) and apply the discounting formula accurately for future values. The mistake was in not correctly accounting for all parts of the endowment and in the misapplication of the discounting formula. The correct answer should reflect the total present value of both his current and future financial resources, accurately discounted if applicable.
