Expressions can also use variables. Variables have a Variant data type and the expression evaluator converts the data type of a variable from a Variant subtype to an Integration Services data type before it evaluates the expression. Variables can use only a subset of the Integration Services data types.
The total COST of each cocktail using 2oz whiskey per drink and using the higher estimate of $90 to buy all ingredients, the startup cost comes out to about $7.5/cocktail. After that first bottle of whiskey is gone, you will surely have PLENTY of the other ingredients left.
Step 4. Multiply the cost per ounce of liquor by the amount added to each drink. You'll need to estimate your liquor cost for each and every drink you serve. If you're pouring one ounce of vodka in your screwdrivers, your liquor cost per drink for a $30 bottle of vodka is 0.91 cents.tep 5. Multiply the liquor cost by four or five to establish the price of the drink. Again, the amount of profit you desire for each drink is determined by you as a bar owner or manager. To earn a 75 percent profit on each drink, multiply your liquor cost by four.
