Question

Mrs. Ebert feeds her dog 1/3 of a cup of dog food twice each day. How long will 6 cups of dog food last?

Answer 1

so, 9 days?

Answer 2

Mrs. Ebert feeds her dog a total of 1/3 + 1/3 = <<1/3+1/3=2/3>>2/3 cup of dog food per day.
Thus, 6 cups of dog food will last 6/(2/3) = 6 * (3/2) = <<6/(2/3)=9>>9 days. Answer: \boxed{9}.

Answer 3

Yes, that is correct. 6 cups of dog food will last for 9 days.
