Understanding Maturity Date Calculation for a 30-Day Note

Explanation:

Maturity Date Calculation: The maturity date of a note is the day when the note is due to be paid. It can be calculated by adding the term of the note to the date it was issued. In this case, a 30-day note dated June 18 would mature 30 days after June 18. When counting days, we typically include the starting day. Hence, the maturity date would be 30 days after June 18, excluding June 18 itself, which results in July 18.

However, it's essential to understand that there are various conventions for counting days in finance, such as the 'actual/actual' or '30/360' conventions. Assuming the most straightforward method of counting days, which is the actual number of days, the correct maturity date for the note is July 18. Therefore, the option B) July 18 is the correct choice.
