Let’s suppose that potatoes (by weight) are 99% water and 1%, well, potato!
If we take a 100 pound bag of potatoes out and put them in the hot June sun, the water will begin to evaporate. If we monitor the moisture content (which starts at 99%, of course) and we weigh the potatoes just when the moisture content gets to 98% (precisely), then how much will the potatoes weigh at that moment?

How much will they weigh when the moisture content is 50%?

Defining "moisture content" as the weight of the wet potatoes minus the weight of the potatoes when completely dry over the weight of the wet potatoes times 100, we find the solution of:

at MC=98% ==> potatoes weigh 50lbs
at MC=50% ==> potatoes weigh 2lbs
