Suppose you buy 100 pounds of potatoes that are 99% water. After leaving them outside for a day, they are now 98% water.


Where is the weight of these slightly dehydrated potatoes?

50 pounds!

Before dehydrate
1% = 1 pound
1 pound not water

After dehydrated
100%-98%=2% not water
2% = 1 pound
100%= 1 x (100%/2) = 50 pounds
