A treasury note with a coupon rate of 3% and expiring on February 15, 2020 has a current bid quote of 98-31. Another treasury note also expiring on February 15, 2020 offers a coupon rate of 5% and has a current bid quote of 99-01.
Explain why these two treasury notes, which expire on the same date, pay a different coupon, and therefore are offered at a different price and yield.
