Final answer:
The T-bill discount is calculated using the par value, purchase price, and days to maturity, and rounds to 3.1% for the given six-month T-bill.
Step-by-step explanation:
To compute the T-bill discount, we use the formula:
Discount = ((Par Value - Purchase Price) / Par Value) * (360 / Days to Maturity)
For the given T-bill, the par value is $10,000, the purchase price is $9,845, and the term is six months, which is equivalent to 180 days. Thus, the discount becomes:
Discount = (($10,000 - $9,845) / $10,000) * (360 / 180) = ($155 / $10,000) * 2
Discount = 0.0155 * 2 = 0.031 or 3.1%
So, the T-bill discount is 3.1%, rounded to two decimal places.
