For a function for 50 guests you require 8.500 kg of trimmed lamb. Trimmings are 20 %. How much lamb do you need to order from stores? Provide your answer to 3 decimal places) 


Also consider the trimming loss when calculating how much raw ingredient is needed to result in the desired amount on the plate. Weigh the trimmed item before cooking (e.g. 250g), roast it and then weigh it after it has been rested to see how much is left (e.g. 200g). Divide the difference between trimmed and cooked weights by the trimmed weight (50g  250g) and multiply it by 100 to get the cooking loss percentage (20%)
