Given that a black Friday offer is available at the supermarket and the offer is to pay within 3 months (Use K = 2) the sum of 45,000.00 for 36 months. The effective rate is 42% capitalizable monthly. We need to determine the value of the screen today, under those conditions.To determine the value of the screen today, we need to use the formula for present value which is given by:P = A(1 + i / k) ^-nkWhere,P = Present ValueA = Future Value (amount to be paid after 36 months)k = compounding frequencyi = annual interest raten = number of years or periodsSo, A = 45,000 and n = 3 years. Since the compounding frequency is monthly, k = 12 and the annual interest rate i = 42%.Substituting the given values in the formula, we get:P = 45000 / (1 + 0.42 / 12) ^ (12 × 3 × 2)P = 45000 / (1.035) ^ 72P = 45000 / 1.335765P = 33,715.90Thus, the value of the screen today is $33,715.90. Hence, the direct answer to the question is $33,715.90.Explanation:In order to obtain the present value of a given sum of money to be paid at some point in the future, the formula for present value is used. The present value formula involves the compounding rate of the interest, the future value, and the number of periods in which the interest is compounded.
