Question

a dog eats 5 cups of food a day. a pound of food contains 10.5 cups. how much does it cost to feed the dog each day if a 50 lb bag costs $22.50?

Answer 1

So, the dog eats 5 cups a day and 1 pound of dog food is 10.5 cups.

A 50 lb bag is $22.50.

Since you're asking how much it would cost to feed it a day we need to find out how much 1 pound of food costs.

22.50 / 50 = 0.45

So, it's 0.45 for 1 lb. But 1 lb is 10.5 cups, not 5.

0.45 / 5 = 0.09

So, I believe it would cost 0.09 each day to feed the dog.
