Question 511108: i have an average of 54 for my first six weeks, what do i have to make on my 2nd and 3rd six weeks to get an average of atleast a 70? Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! 3 periods @ 70 each = 210 total.
You have 54, you need at least 156 more points.
156/2 = 78 each.
Any combination that totals 156 will work, tho.
100 + 56, 90 + 66, etc.
