19. Antonio needs to buy 150 pounds of dog food for the local
dog shelter. The graph shows the relationship between the
number of bags of dog food and the total weight of the do
food at Pets Galore. Another store, Healthy Pets, sells dog
food in 50-pound bags for $85.95 per bag. If one bag of
food from Pets Galore costs $48.15, how much would
Antonio save by buying 150 pounds of dog food from Pets
Galore instead of from Healthy Pets?
