Question: Can you provide an in-depth solution for: A farmer extracts 5 liters of milk a day from a cow. Since he has 3 cows, how many more cows does he need to have to produce 25 liters of milk a day?Hey there, could you help me solve this math problem: A farmer extracts 5 liters of milk a day from a cow. Since he has 3 cows, how many more cows does he need to have to produce 25 liters of milk a day?
Answer: 
He extracts 5*3=15 liters of milk in a day.
He should extract 25-15=10 liters more in a day.
For that, he needs 10/5=2 more cows.
