Explanation

Compound Interest formula: A = P(1 + r)^n. For P=11776, r=12.5%=1/8, n=3: A = 11776×(1+1/8)³ = 11776×(9/8)³ = 11776×729/512 = 16767. CI = A - P = 16767 - 11776 = 4991. Using direct multiplication method: 11776×0.125=1472 (Year 1), then 1472×0.125=184 and 1472×0.125=184 for subsequent years.
