Okay, wild, let's tackle these investment problems. Problem 1: Step 1: Identify the given values for simple interest. The principal amount is P = K4\,000. The time period is T = 3 years. The simple interest rate is R = 20\% = 0.20. Step 2: Use the simple interest formula I = P × R × T. I = K4\,000 × 0.20 × 3 Step 3: Calculate the interest earned. I = K800 × 3 I = K2\,400 The amount of interest earned is K2\,400. Problem 2: Step 1: Identify the given values for compound interest. The principal amount is P = K8\,000. The annual interest rate is r = 10\% = 0.10. The time period is n = 5 years. Step 2: Use the compound interest formula A = P(1 + r)^n. A = K8\,000 (1 + 0.10)^5 Step 3: Calculate the value after 5 years. A = K8\,000 (1.10)^5 A = K8\,000 (1.61051) A = K12\,884.08 Shelly's investment value after 5 years is K12\,884.08.
