Question

Mr. Simpson feeds his dog

Answer 1

Answer:

The total of 4 cups lasts 8 days  to Mr. Simpson.

Step-by-step explanation:

The 1/2 cups of food lasts 1 day

⇒ 1 cup of food lasts = $(\frac{1}{\frac{1}{2} })$   = 2 days.

Now, Mr. Simpson has 4 cups.

So, 4 cups last him = 4 x 2 days   =  8 days

Hence, a total of 4 cups lasts 8 days to Mr. Simpson.
