Final answer:
The cost of not taking the cash discount for Little Kimi Clothiers is 19.05%. The annual rate of interest for the bank loan is 14.50% and the effective annual rate is 15.19%.
Step-by-step explanation:
The cost of not taking the cash discount can be calculated using the formula: Discount % / (100% - Discount %) * (365 / (Payment period - Discount period)). In this case, the discount % is 3/19, the payment period is 90 days, and the discount period is 19 days. Plugging these values into the formula, we get:
The cost of not taking the cash discount % = (3/19) / (1 - (3/19)) * (365 / (90 - 19)) = 19.05%.
Based on this calculation, Little Kimi Clothiers would need to pay an additional 19.05% on the amount if they choose not to take the cash discount. Regarding the second question, to calculate the annual rate of interest, divide the interest amount by the principal and multiply by 365/days. In this case, the interest amount is $93, the principal is $6,000, and the time period is 45 days. Plugging these values into the formula, we get:
The annual rate of interest % = ($93 / $6,000) * (365 / 45) = 14.50%.
To calculate the effective annual rate, use the formula: (1 + (Annual rate of interest / 100)) ^ (365 / days) - 1. In this case, the annual rate of interest is 14.50% and the time period is 45 days. Plugging these values into the formula, we get:
Effective annual rate % = (1 + (14.50% / 100)) ^ (365 / 45) - 1 = 15.19%.
