Final answer:
To calculate how much more Kasamba will pay on hire purchase, we need to compare the total cost for cash and on hire purchase. The total cost for cash is k4200, and the total cost on hire purchase is k5280. Therefore, Kasamba will pay k1080 more on hire purchase.
Step-by-step explanation:
To calculate how much more Kasamba will pay on hire purchase, we need to compare the total cost of buying the radio in cash with the total cost of buying it on hire purchase.
For cash:
Total cost = k4200
For hire purchase:
Total cost = Deposit + 9 monthly installments
Total cost = k1500 + (9 x k420)
Total cost = k1500 + k3780
Total cost = k5280
Therefore, Kasamba will pay k5280 - k4200 = k1080 more on hire purchase.
