This problem cannot be solved.
There are three unknowns in this problem. They are the number of cups of each size for three different sizes;
Three consistent equations involving three variables are needed to solve this
Total number of cups of coffee sold ......(Eq 1)
Total money collected from the sell ......(Eq 2)
However, number of 96 oz pots involves one variable only.
