Bill a monthly group class its fee once per month

A monthly group class multiplied its price by the sessions falling in the month, the same rule private lessons use — so a class priced at 40.00 CAD meeting weekly was billed 160.00 CAD on the 1st, and no studio could quote the price on a class card without lying about it. A group class is now billed its fee once for the month however many times it meets, which is what the card quotes and what the student ticks to agree to. Private lessons keep the per-lesson rule: their price is a per-lesson fee, and that is why the card quotes it per lesson. The session count still labels the month on the student's payment notice; it no longer prices it. Co-Authored-By: Claude Opus 5 <[email protected]>
