Question 7 • Advanced Financial Algebra
Use the compound interest formula with the number of compounding periods over 2.5 years. Bank A compounds monthly, so it has 12 × 2.5 = 30 periods: $3,500(1 + 0.0365/12)^30 ≈ $3,833.87. Bank B compounds quarterly, so it has 4 × 2.5 = 10 periods: $3,500(1 + 0.0365/4)^10 ≈ $3,832.81. These amounts match the choice listing $3,833.87 for Bank A and $3,832.81 for Bank B.
