Q: In North Carolina, Jim bought 10 gallons of gas at $2.00/gallon. He paid $1.00 more per gallon in Virginia where he bought another 10 gallons of gas. How much has he spent on gas?
A: In North Carolina, he bought 10 gallons at $2.00 / gallon for a total of 10 * 2 = $20.00. He paid $2.00 a gallon in North Carolina and $1.00 more in Virginia for a total of 2 + 1 = $3.00 / gallon. He bought 10 gallons at $3.00 / gallon in Virginia for a total of 10 * 3 = $30.00. He spent $20.00 in North Carolina and $30.00 in Virginia for total of 20 + 30 = $50.00. The answer is 50.
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: 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. The answer is 39.
[Question]Matilda had 20 chocolate bars and shared them evenly amongst herself and her 4 sisters. When her father got home from work, he was upset that they did not put aside any chocolates for him. They felt bad, so they each gave up half of their chocolate bars for their father. Their father then gave 3 chocolate bars to their mother and ate 2. How many chocolate bars did Matilda's father have left?
[Answer]Matilda and her sisters each got 20 chocolate bars / 5 people = 4 chocolate bars / person. They each gave 4 / person / 2 = 2 chocolate bars / person to their father. Their father received 2 chocolate bars / person x 5 people = 10 chocolate bars. Their father had 10 chocolate bars - 3 chocolate bars - 2 chocolate bars = 5 chocolate bars left. The answer is 5.
