Question: This math problem has got me stumped: Elijah drank 8.5 pints of coffee yesterday. Emilio drank 9.5 pints of water yesterday. How many cups of liquid did the two boys drink yesterday?
Can you show me the way?
Answer: 
Total drunk: 8.5 + 9.5 = 18 pints
18 pints * 2 = 36 cups
The two boys drank a total of 36 cups of liquid yesterday.
