large dogs:  1 1/4 pounds per day

question 1): is the cat food or dog food cheaper by the pound?

question 2): is it cheapest to feed a cat, small dog, or large dog each day?

Answer 1

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

   5

 

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

          10                                                            10

 

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.
