To find the mean, you have to find the sum of all of the number amounts. That equals 28. Then you divide the sum with the amount of numbers you added up, which in this case would be 7. 28/7 is 4.
You're answer would be 4. I hope this helps :)

Answer:
6400
Step-by-step explanation:
Given the profit function ;
P(c) = –20c2 + 320c + 5,120
The maximum value is given by :
f(h) ; where, h = - b /2a
From P(C) ; a = - 20 ; b = 320
h = - b / 2a = - 320 / 2(-20) = - 320 / 40 = 8
c = h
P(8) = –20(8)² + 320(8) + 5,120
P(8) = - 1280 + 2560 + 5120
= 6400
