Let me give you a tip use M= y1-y2/x1-x2 to find the slope with to points
If the 5 scores have a mean of 8, then their total sum would be 8*5 = 40
Now if one score if added (let's call this score x), there are 6 scores and the mean changes to 9, thus:
(40 + x)/6 = 9
40 + x = 54
x = 14
I believe your length would be 8, because -3 to get to 0 is 3 then after that you still have 5 so you add them and get 8
500 - 116 = 384 left to collect
384 divided into 3 weeks = 128
They must collect $128 per week in order to reach their goal of $500.
