If John scored 100 on his first 3 tests and an 80 on his 4th, what was his average score across the 4 tests?
100+100+100+80=<<100+100+100+80=380>>380 total score across 4 tests
380 total score / 4 tests = <<380/4=95>>95 average score
#### 95
John ilk 3 testten 100 ve 4. testten 80 puan aldıysa, 4 testteki ortalama puanı nedir?
100+100+100+80=<<100+100+100+80=380>>4 testte toplam 380 puan
380 toplam puan / 4 test = <<380/4=95>>95 ortalama puan
