Answer:
88.8%
Step-by-step explanation:
1.) 30-18= 12 which is the number of member that had an average of 84
2.)Then multiply 12 times 84 = 1008
3.) You multiply 18 by 92 which equals 1656
4.)Add 1008 and 1656 together and get 2664.
5.)Divide 2664 / 30 and you get the average of 88.8

A) The revenue = Price (p) * Quantity sold (x)
From the inequality p = 1, 2, 3 ...18
The revenue as a function of quantity sold = R(x)
But R = p * x = px
And x = -8p + 144.
Hence we have R(x) = p( -8p + 144) = - 8p^2 + 144p where p lies between 1 and 18.
B) If the quantity sold, x, is 88 then 88 = -8p + 144; -8p = 88 - 144. We have that p = 7
Then it follows that revenue = 7 * 88 = 616
C) Since R (x) = - 8p^2 + 144p Then dr/dx = -16x + 144. Then we set dr/dx
= 0. So x = 144/ 16 = 9
Then we use x to calculate p as follows. 9 = -8p + 144. Hence p = 135/8 = 16.875
At maximum revenue we have R(x) = - 8(16.875)^2 + 144(16.875) = -2278.56 + 2345.56 = $66.48
D) From C) The company should charge 16.875.
If R = 520. Then 520 = -8p^2 + 144p
So -8p^2 + 144p - 520 = 0
From the quadratic equation our equation becomes x1 = 13 and x2 = 5. We simply substitute
-8(13)^2 + 144(13) - 520 = 0. Hence our answer is 13
