What about .2 tips?
Well, those are for you to fill down. Go ahead and write formulas for both these situations & you have the .2 tips!
18.1 Waiter friendly pricing
Lets say you run a hotel where customers usually tip 15% of bill amount. Now, to make it easy, you want to price your items such that when 15% is added, the total amount becomes a round number like $1.00, $2.00 etc.
For example: If a dish’s current price is $2.50, then 15% tip on it would be $0.37. This makes the total $2.87.
If you modify the price to $2.60, with tip the total would be $3.00.
Assuming current price of a dish is in A1, what formula will give you new price?
