Required:

Compute the annual interest rate implicit in the sales discount. (Use 365 days in a year. Do not round intermediate calculations. Enter your answer as a percentage rounded to 2 decimal places (i. e. 0.1234 should be entered as 12.34).)

Answer: 28.20%

Explanation:

To compute the annual interest rate implicit in the sales discount for thus:

Firstly, we have to calculate the difference that exist between the payment date and the due date and then divide by 365 days which has been given in the question. This will be:

= 60 days - 20 days = 40 days

= 365days/40days

= 9.125%

Secondly, we will then subtract the percentage discount from 100% and then divide the result. Since discount percentage is 3%, this will be:

= 3% / (100% - 3%)

= 3%/97%

= 0.03/0.97

= 0.0309278351

= 3.09%

Lastly, we then multiply the result of the calculations above together in order to get the annualized interest rate. This will be:

= 9.125% * 3.09%

= 28.19625%

= 28.20%

Annualized interest rate. = 28.20%
