analyse 1.4 response of learner in this format: In analysing the responses of Learner S1, S2, and S3, it is clear that each learner approached the problem with varying levels of understanding and application of mathematical concepts. Learner S21 demonstrated a strong ability to connect theoretical knowledge with practical application. They effectively showed the key components of the problem and applied the correct formulas to calculate the total cost of the armchair, including the deposit and interest over the specified period. Learner S2 showed a moderate understanding, correctly calculating the deposit but struggled with applying the interest formula accurately, leading to a slight miscalculation in the total cost. Learner S3, on the other hand, faced challenges in both showing the correct components and applying the formulas, resulting in an incorrect final answer. This analysis highlights the importance of a clear understanding of financial mathematics concepts and the ability to apply them accurately in problem-solving scenarios
