Today is March 1, 2011. Devi has $4,908.05 and wants to buy a T-bill with a face value of $5,000 that matures on December 12, 2011. The annual simple discount rate is 2.750% and the daycount convention is ACT / 360.

a) How much would the T-bill cost if she were to purchase it today?

b) How much interest would she earn every day (if the discount rate stayed constant)?

c) If Devi doesn't buy the T-bill today, what is the last day on which she will still be able to buy it?
