Question 1107463
the juice recipe says that you mix 8 parts of water with 1 part of sugar and  part of flavoring.


add up the parts and that totals 10 parts.


divide 20 gallons by 10 and you get 2 gallons for each part.


that means 8 * 2 = 16 gallons of water plus 1 * 2 = 2 gallons of sugar plus 1 * 2 = 2 gallons of flavoring.


you get 16 gallons of water plus 2 gallons of sugar plus 2 gallons of flavoring for a total of 20 gallons of juice.


your solution is that you need 2 gallons of sugar.
