find the variables of this passage Evan wants his dog to be healthy. He decides that if his dog, Scrappy, loses weight, then he will be more healthy. So, the first thing he decides to do is try out different dog foods. Each week, he feeds Scrappy 3 times a day: once at breakfast, once for lunch, and once for dinner. When he feeds Scrappy, he gives him 250cc of dog food. The first week Evan feeds Scrappy with Skinny-O’s, the next week was Yummy-O’s, and the last week Scrappy was given Healthy-O’s. Before he changed the food, Evan weighed Scrappy at 3 in the afternoon and he weighed 14 kg. At the end of each week, he weighed at 3 in the afternoon, and it turns out he lost the most weight when he was eating Healthy-O’s.
