# GSM8K Problem 5

Every day, Wendi feeds each of her chickens three cups of mixed chicken feed, containing seeds, mealworms and vegetables to help keep them healthy.  She gives the chickens their feed in three separate meals. In the morning, she gives her flock of chickens 15 cups of feed.  In the afternoon, she gives her chickens another 25 cups of feed.  How many cups of feed does she need to give her chickens in the final meal of the day if the size of Wendi's flock is 20 chickens?

Reason step by step, then give ONLY the final answer on the last line as \boxed{ANSWER}.

<!-- imported from openai/gsm8k (test) -->

We are told:

- Wendi has **20 chickens**.
- Each chicken gets **3 cups of mixed feed per day**, so total daily feed =  
  $ 20 \text{ chickens} \times 3 \text{ cups/chicken} = 60 \text{ cups} $.

She gives feed in **three meals**:

- Morning: 15 cups  
- Afternoon: 25 cups  
- Final (evening) meal: ?  

Total given so far:  
$ 15 + 25 = 40 $ cups.

So, remaining feed for the final meal:  
$ 60 - 40 = 20 $ cups.

\boxed{20}
