$70 per hour
High school Algebra, Geometry, Trigonometry, pre-Calculus:
$60 per hour
Block discounts:
Prepay 5 hours:    10% off
Prepay 10 hours:  15% off
Prepay 20 hours:  20% off
Billing procedures:
If you do not wish to prepay, I will send you a statement by email at the end of each month to bill (at the full price as listed above) for that past month's sessions. I'll expect payment at or before the next session.

If at any time you pay in advance for 5 or more hours, I'll apply the discounted rate (as listed above) to all prepaid sessions on or after the date of that payment.

Payment accepted by check (preferred), credit card, PayPal, or Apple Pay.

Our very first session is a trial: If you decide to continue with me, it will be billed as usual, but if you decide not to continue, there will be no charge for it.

I will share with you a web link to a private google spreadsheet which will show all sessions, payments, hours done, prepaid hours balance, etc, which you can access at any time.

And finally, if any of the above is not perfect for you, I'm open to negotiation! ;-)
