Note
Simple discount is sometimes used to
determine the proceeds of a promissory note
sold before maturity
Example 1.5.2

Jones and signs a promissory note due in 6
months at r = 8%. On July 30, Jones sells the
note to Brown who discounts the note at a
simple discount rate of d = 9%.
a) What price does Jones received for selling the
note?
b)What rate of return does Brown earn if the
note is held to maturity?
