Simple Excel file Formula additions

Using the excel template and already existing formulas
I want to add "levers to modify" of

Average Customer Spend:
Average Daily Customers:

those two should be added to the sheet and in yellow

Changing those levers should change the gross revenue which should change the rest of the excel sheet including the net profit
everything should corollate

Changing the average customer spend and daily customers should change the daily avg gross revenue, annual net profit, gross revenue, ebitda %.

Chaging the gross revenue should change the daily avg gross revenue, annual net profit, gross revenue, ebitda %.

Changing the avg customer spend should change the daily avg gross revenue, annual net profit, gross revenue, ebitda %

Changing the avg daily customer hould change the daily avg gross revenue, annual net profit, gross revenue, ebitda %

Changing both the avg daily spend and # of customers should effect the avg daily gross revenue which should change annual net profit, gross revenue, ebitda %

etc etc

please make these changes and formula additional on all 4 excel files and clean up / remove the excess page on the right.
