If a six- month Treasury bill is purchased for $ 0.9675 on a dollar ( i. e., $ 96,750 for a $ 100,000 bill), what is the discount yield, the annual rate of interest, and the compound rate? What will these yields be if the discount price falls to $ 0.94 on a dollar ( i. e., $ 94,000 for a $ 100,000 bill)?
