# 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) -->

First, we need to determine the total amount of feed required for the entire flock of chickens for the day.
There are 20 chickens, and each chicken needs 3 cups of feed per day.
Total feed needed = 20 chickens * 3 cups/chicken = 60 cups.

Next, we calculate how much feed has already been given to the chickens in the morning and afternoon meals.
Morning feed = 15 cups
Afternoon feed = 25 cups
Total feed given so far = 15 cups + 25 cups = 40 cups.

Finally, we subtract the amount of feed already given from the total amount needed to find out how much is required for the final meal.
Feed needed for final meal = Total feed needed - Total feed given so far
Feed needed for final meal = 60 cups - 40 cups = 20 cups.

\boxed{20}
