Final answer:
The maturity date of a 30-day note dated June 18 is July 18, following a straightforward counting method where the starting day is not included. Therefore, the correct answer is B) July 18.
Step-by-step explanation:
The maturity date of a note is the day when the note is due to be paid. The maturity date 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 normally include the starting day. Thus, the maturity date would be 30 days after June 18, not including June 18 itself, which is July 18. If we include June 18, that would be 29 days later, making July 17 as the maturity date.
However, it is important to know that there are different conventions for counting days in finance, such as the 'actual/actual' or '30/360' conventions. Assuming the most straightforward method of counting, which is the actual number of days, the correct answer for the maturity date of the note is July 18. This makes option B) July 18 the right choice.
