Question: A shopkeeper bought 150 packets of milk. Each packet contained 250 ml of milk. If one fluid ounce is equal to 30 ml, how many ounces of milk did he buy?
Answer with step-by-step thinking: If the shopkeeper bought 150 packets of milk, each packet containing 250ml of milk, all the packets had a total of 250 * 150 = 37500ml. Since one ounce equal 30 ml, the total amount of milk that the shopkeeper bought in oz is 37500 / 30 = 1250 oz of milk.
So the answer is 1250.


Question: Darius has 5 buckets of water. One contains 11 ounces, one contains 13 ounces, one contains 12 ounces, one contains 16 ounces, and one contains 10 ounces. He pours the ten-ounce bucket into a bigger bucket, along with one of the other four. The total in the bigger bucket is now 23 ounces. He pours the remaining three buckets into a second large bucket. How many ounces does the second large bucket contain?
Answer with step-by-step thinking: Darius poured the 13 - ounce bucket into the first large bucket because 23 - 10 = 13. The remaining buckets are thus the 11, 12, and 16 ounce buckets. The second large bucket contains 39 ounces because 11 + 12 + 16 = 39.
So the answer is 39.


Question: A restaurant is offering a fundraiser one day where they donate $2 for every $10 donated by customers. The average customer donates 3 and there are 40 customers that day. How much does the restaurant donate?

So the answer is 24.
