How to bet P4, p5 and Rainbow under new rules

[$bill]

If you are playing p4,P5 and rainbows using the Steve Crist method, how do you bet now? for example.:

If you bet a back up ticket that costs $2 and hit for $700 do you get taxed as before if it's the only bet on your ticket?

If you put a 2nd back up ticket for another $2 on same ticket then are you OK?

How do you put multiple bets/tickets together when betting online?

Thanks for any guidance
