Let S=score on the second exam, then
(67+S+(S+7))/3=84

2S+74=252
2S=178
S=89
So second exam: 89
third exam=89+7=96
Check: (67+89+96)/3=84 ok.
<span>Let me help you doing it like this: Given the data you simply need to multiply the number of choices for each part together to get the total number of ways soitwill be
