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?
How many points did Henry score on his first 3 tests? ** The sum of his scores across the first 3 subjects is 50+70+66 = <<50+70+66=186>>186
What is the average score of Henry's first 3 tests? ** The average score over the 3 subjects which is his History score is = total/3 = 186/3 = <<186/3=62>>62
What was Henry's total score across all 4 subjects? ** Therefore his score across all 4 subjects = 186+62 = <<186+62=248>>248
