Deion is purchasing cat food. The brand he plans to buy comes in two seizes. •The small bag weighs 3 pounds,

Last time, Deion purchased the small bag that weighs 3 pounds, which costs 15$. This time, he is planning on buying the large bag that weighs 8 pounds. If both bags cost the same amount per pound, how much total (in dollars) does the large 8-pound bag of cat food cost?
