Matthew drinks 4 glasses of water per day. Each glass is 5 ounces. He decides to just buy a 35 ounces water bottle. How many times will he fill it each week? Give me reasons, before answering the question
He drinks 20 ounces of water a day because 4 x 5 = 20. The drinks 140 ounces in a week because 7 x 20 = 140. He will fill it up 4 times because 140 / 35 = 4. So the final answer is 4.
