To calculate the effective rate, we need to determine the yield of the Treasury bill. The formula to calculate the yield is:

Yield = (Face Value - Purchase Price) / Purchase Price

In this case, the face value is $10,000.00, and the purchase price is not given. However, we know that the Treasury bill is bought at a discount of 5%.

To find the purchase price, we can use the formula:

Purchase Price = Face Value - Discount

To calculate the discount amount:

Discount = Face Value * (Discount Rate / 100)

Now we can substitute the values into the formulas:

Discount = $10,000.00 * (5 / 100) = $500.00

Purchase Price = $10,000.00 - $500.00 = $9,500.00

Using the purchase price, we can calculate the yield:

Yield = ($10,000.00 - $9,500.00) / $9,500.00 = 0.0526 (rounded to 4 decimal places)

Finally, to convert the yield to a percentage, we multiply by 100:

Effective Rate = 0.0526 * 100 = 5.26%

Therefore, Annika Scholten's effective rate on the Treasury bill is 5.26% (rounded to the nearest hundredth percent).
