You're on a roll — The image contains two distinct parts: a compound interest problem and a definition of depreciation. For the compound interest problem: The principal amount (initial investment) is missing from the visible text. Without this value, the exact interest and total amount cannot be calculated. However, if we denote the principal amount as P: Given: Interest rate (r) = 12% per annum = 0.12 Time (t) = 7 years The formula for the total amount (A) after t years with compound interest is: A = P(1 + r)^t The formula for the compound interest (CI) earned is: CI = A - P Substituting the given values: A = P(1 + 0.12)^7 A = P(1.12)^7 A ≈ P(2.21068) And the compound interest would be: CI = P(1.12)^7 - P CI ≈ P(2.21068) - P CI ≈ P(1.21068) To get a numerical answer, please provide the principal amount. For the definition of Depreciation: Depreciation refers to the decrease in the value of an asset over a period of time due to wear and tear, obsolescence, or usage. It is typically expressed as a percentage of the original value. For example, if an asset depreciates by 5%, its new value is (100 - 5)% of its original value. Depreciation is the decrease in an asset's value over time due to factors like wear, tear, or obsolescence. Got more? Send 'em 📸
