The present value of Peregrine's endowment can be calculated by adding the present value of his earnings to his current consumption. The present value of his future earnings (2,040) discounted at a 20% interest rate is 2,040 / (1 + 0.20) = 1,700. Adding his current consumption (1,400) gives a total of 3,100. However, since Peregrine also consumes in the future (1,440), we need to subtract this future consumption discounted at the interest rate: 1,440 / (1 + 0.20) = 1,200. Therefore, the present value of his endowment is 3,100 - 1,200 = 1,900. However, it seems there was a mistake in my calculation as none of the provided options match the result. Let's correct the approach:To find the present value of Peregrine's endowment, we should consider his current consumption and the net present value of his future transactions. Given the interest rate is 20%, we calculate the present value of his future earnings and subtract any future consumption or costs.The correct calculation should involve adding his current assets or earnings and then adjusting for the time value of money for any future earnings or consumptions. However, without the explicit future consumption or earnings timing, a direct calculation mistake was made in my initial explanation. The correct approach is to consider all available assets and earnings, then discount any future amounts back to their present value at the given interest rate. Since the provided numbers and the interest rate do not directly lead to a straightforward calculation without additional assumptions on timing and without making a calculation error, let's correct the oversight:Given the initial mistake in calculation and explanation, the correct answer should be derived by accurately calculating the present value of Peregrine's endowment considering his consumption and earnings at the given interest rate. However, without further details on the timing of future earnings or consumption, a precise recalculation cannot be provided here based on the initial incorrect explanation. The correct answer should align with the options given, assuming proper calculation of present values and considering all aspects of Peregrine's financial situation.
