During the 1787 convention in Philadelphia when the constitution was being formed by the founding fathers, their sessions would usually end in heated arguments and disagreements.
To calm the delegates after the draining sessions, Benjamin Franklin who was then mostly in his home and 81 years old at that time, came up with the idea of entertaining the delegates in his home with the cold cream. His idea was helpful in reducing tensions.
First, divide 325 by 4, which will come out to be 81.25, then take the 85 that his mom gave him and subtract the 81.25 to get your answer, which is, 3.75 :)
