Answer:To find the simple interest on Nanay Aning's loan, we use the simple interest formula:Interest (I) = Principal (P) × Rate (R) × Time (T)Where:- P = 35,500 (the amount borrowed)- R = 7% or 0.07 (the interest rate as a decimal)- T = 3 years (the time period)Now, calculate the interest:I = 35,500 × 0.07 × 3 I = 35,500 × 0.21 I = 7,455So, the interest on Nanay Aning's loan after 3 years is P7,455.
