Help with a Math Formula

[Runnin' Rebel]

Here it is:

cash gratuity breakdown on a 1000k dinner check

1000.00 gross revenue
- 81.00 sales tax (8.1%)
___________
919.00 net revenue
x 23 % gratuity
___________
211.37 total gratuity


919.00 x 5% = 45.95 Resturant gratuity, (they take this for themselves out of the after tax net).

919.00 x 18%= 165.42- Server gets 86% of this, RESTURANT gets 14% as shown below
________________
23%= 211.37 total gratuity

165.42 x 86% = 142.26 food server gratuity
165.42 x 14% = 23.16 house gratuity
_________
165.42

Food Server total gratuity = 142.26
Resturant total gratuity (45.95+23.16)= 69.11
__________
211.37

I'm trying to do this on a calculator by deducting the tax, what the RESTURANT takes and what the final tip is for the food server in an easier way

There's a formula that is easier that can be done on a calculator in like 3 easy steps.

Total bill minus tax and what they siphon off from the food server gratuity and what she would get without going through all of the above.


Someone see if they can figure it out please
Thank you

If you could use an a few different totals that would help. Like the check is 2345.54 etc..
