Question 3 3.1 Rick is considering two different ways in which he could pay for a second-hand car, on offer from a dealer for 2000: Option A: A 2000 car loan from his bank, repayable in monthly instalments over 2 years at an APR of 5.5% Option B: The dealer's own 2000 loan, secured against the car, repayable in monthly instalments over 5 years at an APR of 6.5% Calculate the total amounts of interest that Rick will pay under Option A and Option B. Give one reason why, in spite of these results, Rick might prefer to use Option B. (4 marks). 3.2 Exploring Option B, Rick examines what will happen if he misses a repayment and does not make up for this by making an equivalent over-payment soon after. He finds that if he misses one monthly repayment in Year 4, it adds much less to his total interest payment over five years than if he misses one monthly repayment in Year 1. Briefly explain why this is the case.
