Textbook Problem

Boz Foster signed a $10.000 simple discount promissory note at a bank discount rate of 6%. If the term of the note was 125 days, what was the effective interest rate of the note? Round your answer to the nearest hundredth of a percent. To determine To calculate: The amount of bank interest, purchase price and effective rate of interest of the simple discount promissory note purchased by Boz Foster which has face value of$10,000 with discount rate is 6% and for duration of 125 days.

Explanation

Given Information:

Face value is $10,000, interest rate is 6%, time period is 125 days. Formula used: Evaluate the time for ordinary interest as, Time=Number of days of a loan360 The formula to calculate effective rate of interest is, Effective interest rate=InterestPurchase Price×Time The formula to compute the amount of bank interest is, Bank Discount=Face value×Discount Rate×Time The formula to calculate purchase price is, Purchase Price=Face valueDiscount Calculation: Consider that face value of loan is$10,000, interest rate is 6% and time period is 125 days.

Compute the interest amount,

Simplify the interest rate as,

6%=6100=0.06

Evaluate the time for ordinary interest as,

Time=Number of days of a loan360=125360

Substitute $10,000 for face value, 0.06 for interest rate and 125360 for time in the formula Bank Discount=Face value×Discount Rate×Time. Bank Discount=Face value×Discount Rate×Time=10,000×0.06×125360=$208.33

Hence, amount of interest is \$208
