What is the cost per pound of the dog food given the bag size, daily serving, and cup weight?

• A. $0.23 per pound
• B. $2.34 per pound
• C. $0.43 per pound
• D. $4.98 per pound

Answer: (C)

The main idea is to express the price in dollars per pound by dividing what you pay for a bag by how many pounds you get in that bag. To connect the daily serving and cup weight, you can convert all quantities to pounds so you can see how much food is eaten each day, but that daily amount is used to check cost over time rather than change the per‑pound price itself. First convert the weight of a cup to pounds: pounds per cup = cup weight in ounces divided by 16. Then find how many pounds are eaten each day: pounds per day = daily serving (in cups) times pounds per cup. The cost per pound is determined by the bag price divided by the bag’s weight in pounds: price per pound = bag price / bag weight in pounds. If you multiply the daily pounds by this price per pound, you get the daily cost, while the per‑pound figure itself remains fixed at bag price divided by bag weight. Using the values from the problem, that per‑pound cost comes out to about $0.43.
