conversations.value: Can you explain how to solve this math problem: Henry scored 50 points on his Geography test, 70 on his Math test and 66 on his English test. If his History score is the average of these 3 scores, what was his total score across all 4 subjects?
conversations.from: assistant
conversations.value: The sum of his scores across the first 3 subjects is 50+70+66 = 186
  The average score over the 3 subjects which is his History score is = total/3 = 186/3 = 62
  Therefore his score across all 4 subjects = 186+62 = 248
