An adult participant (who is not a student) registers for the workshop and both optional sessions on August 10, 2026, paying the full amount due. On September 20, 2026, the participant cancels their registration. Based on the flyer, what is the total refund amount this participant is entitled to receive?

  1. A
    $425.00
  2. B
    $466.25

  4. D
    $839.25

Answer

The refund amount is $361.25, which corresponds to 50% of the discounted early-bird registration fee.
The participant registered on August 10, which qualifies them for the 15% early-bird discount, making their registration fee 722.50.OnSeptember20,whichis22daysbeforetheOctober12startdate,theparticipantcancelled.ThiscancellationdatefallsintotheSeptember13toSeptember28window.Thepolicystatesthatduringthisperiod,theparticipantisentitledtoa50722.50. On September 20, which is 22 days before the October 12 start date, the participant cancelled. This cancellation date falls into the September 13 to September 28 window. The policy states that during this period, the participant is entitled to a 50% refund of the registration fee paid ( 361.25) and that optional session fees are completely non-refundable.

Step-by-Step Solution

1
Determine the initial amount paid for the registration fee.
Since registration occurred on August 10 (before the August 15 deadline), the early-bird discount of 15% applies: 850(0.15850 - (0.15 * 850) = $722.50.
This establishes the actual base registration cost paid by the participant.
2
Determine the cost of optional sessions and calculate total paid.
Optional sessions cost 120and120 and 90, making the total paid 722.50+722.50 + 120 + 90=90 = 932.50.
This identifies all financial components that could be affected by the cancellation policy.
3
Identify the cancellation window based on the date.
The cancellation date is September 20, 2026. This falls between September 13 and September 28, which is 22 days prior to the start of the workshop.
This maps the date to the correct refund policy tier in the flyer.
4
Apply the refund rules of the identified cancellation window.
The refund is 50% of the registration fee paid (722.500.50=722.50 * 0.50 = 361.25), and optional fees are non-refundable (0).Thetotalrefundis0). The total refund is 361.25.
Applying these rules gives the final correct refund amount.
