Answer: An investor could buy this bill for $9837 .
We follow these steps to arrive at the answer:
First we calculate the interest on the bill for 180 days, assuming that the value of the T-bill is $1.

[tex]Interest on the bill = 0.0326 * \frac{180}{360}[/tex]

A t-bill doesn't pay interest; instead the interest amount is deducted from the Face Value in order to arrive at the purchase price.
If the face value of the t-bill is $1, the purchase price is

Since the actual face value of the t-bill is $10,000, the purchase price is
