Three students, Linda, Tuan, and Javier, are given laboratory rats for a nutritional experiment. Each rat's
weight is recorded in grams. Linda feeds her rats Formula A, Tuan feeds his rats Formula B, and Javier
feeds his rats Formula C. At the end of a specified time period, each rat is weighed again, and the net gain
in grams is recorded.
