Cat food sold at store is $5.98/10 pounds
Dog food sold at store is $24.50/50 pounds
Let's make the problem easier by making the weight equal to one another. Divide $24.50 by 5 to get the price of 10 pounds of dog food.
$24.50/50 pounds = $4.90/10 pounds dog food
10 pounds of cat food costs $5.98 and 10 pounds of dog food costs $4.90. Answer to Question 1: The dog food is cheaper by the pound.
The second question requires us to analyze the price of pet food by the pound. So let's simplify the cost of the food even further to find how much cat food cost contrasts to dog food cost per 1 pound. Divide $5.98/10 pounds by 10 to get the cost of cat food per pound and divide $4.90/10 pounds by 10 to get the cost of dog food per pound.
$5.98/10 pounds = .598/1 pound $4.90/10 pounds = .490/1 pound
Lastly, the price of feeding each type of animal needs to be contrasted to learn which animal is cheapest to feed. As stated, each animal requires a different amount of food on a daily basis. Multiply the designated weight of food with the cost of the food to find how much it costs to feed each type of animal each day.
Cat: .598 x (1/3) = .19933
Small Dog: .490 x (1/2) = .245
Large Dog: .490 x (1.25) = .6125
Answer to Question 2: The cat is the cheapest to feed each day.
