Question 21 • Financial Math
Both balances start at $4,000, so compare their growth factors: Aahil’s is 1 + 0.035t, and Zuri’s is e^(0.03t). After 10 years, Aahil’s factor is 1.35, while Zuri’s is e^0.3 ≈ 1.3499, so Zuri is still slightly behind. After 11 years, Aahil’s factor is 1.385 and Zuri’s is e^0.33 ≈ 1.391, so Zuri has pulled ahead between years 10 and 11. This matches choice B, between the 10th and 12th year.
