Question

In one day a 20 pound dog eats 3 cups of food. How much would a 50 pound dog eat​

Answer 1

We can use proportions to solve the problem:

Let x be the amount of food (in cups) that a 50 pound dog eats in one day.

Since the amount of food eaten is directly proportional to the weight of the dog, we can set up the following proportion:

20 pounds / 3 cups = 50 pounds / x cups

To solve for x, we can cross-multiply:

20 pounds * x cups = 3 cups * 50 pounds

20x = 150

x = 7.5

Therefore, a 50 pound dog would eat approximately 7.5 cups of food in one day, assuming that the amount of food eaten is directly proportional to the weight of the dog.
