Final answer:
The investor owes 130 days of accrued interest on the T-notes, from purchase on February 20th to maturity on July 1st, calculated by adding the actual days in each month within the period.
Step-by-step explanation:
To calculate the number of days of accrued interest the investor owes, we need to count the days from the purchase date, February 20th, to the maturity date, July 1st, of the T-notes. The count is done on a cash basis, meaning actual days are counted rather than using a standard 30-day month. Since it's not a leap year, February has 28 days. Then, we calculate the number of days in March, April, May, and June, which are all 31 days each. Finally, we calculate the number of days in July up until the 1st, which is 1 day. Adding up all these days, we have:
28 days (February) + 31 days (March) + 30 days (April) + 31 days (May) + 30 days (June) + 1 day (July 1st) = 151 days.
Therefore, the investor owes 151 days of accrued interest.
The number of days each month that should be counted is calculated as follows:
- February: 8 days (from 20th to 28th, assuming it's not a leap year)
- March: 31 days
- April: 30 days
- May: 31 days
- June: 30 days
- July: 1 day (the maturity date itself is not included in accrued interest calculation)
When you add up the days from each month, you get:
Total days = 8 (February) + 31 (March) + 30 (April) + 31 (May) + 30 (June) + 0 (July) = 130 days of accrued interest.
