Madeline wants to drink 100 ounces of water in a day. Her water bottle can hold 12 ounces of water. She refills her water bottle 7 times. How much more water does she need to drink? Give me reasons, before answering the question
She has already had 12 * 7 = 84 ounces of water. She needs to drink 100 - 84 = 16 more ounces to make it to 100 ounces. So the final answer is 16.
