Over the past 35 years, the prevailing market yield or discount rate on 90-day T-bills has ranged from a low of 0.17% in February 2010 to a high of 20.82% in August 1981. (The period from 1979 to 1990 was a time of historically high inflation rates and interest rates.)

How much more would you have paid for a $100,000 face value 90-day T-bill at the February 2010 discount rate than at the August 1981 discount rate? (Round your answer to the nearest cent.)
