# 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) -->

Step 1: Determine the total amount of feed Wendi gives her chickens each day.
Each chicken gets 3 cups of feed per day.
Wendi has 20 chickens.
Total daily feed = 3 cups/chicken × 20 chickens = 60 cups.

Step 2: Calculate the total amount of feed already given in the morning and afternoon.
Morning feed = 15 cups.
Afternoon feed = 25 cups.
Total given so far = 15 cups + 25 cups = 40 cups.

Step 3: Find the amount of feed needed for the final meal.
Total daily feed needed = 60 cups.
Feed already given = 40 cups.
Feed needed for final meal = 60 cups - 40 cups = 20 cups.

\boxed{20}
