There is a cake made for the birthday of an analytics professional. Altogether, there are five persons at the party. However, one person, as a trick, has cut the cake into 15 slices with weights (in grams) of 18, 48, 19, 59, 46, 72, 67, 57, 49, 80, 50, 69, 10, 48, 83. The goal is to give all of the pieces out in a way that is most fair (that is, everyone receives an equal share).Formulate this as an integer program and find a solution via Solver.
