Step-by-step explanation:
The revenue from sales of fans is the product of the number of fans sold and the price at which they are sold:
R(p) = n·p = (1960-70p)p
R(p) = 70(28 -p)p
This equation describes a parabola that opens downward and has zeros at p=0 and p=28. The axis of symmetry is halfway between those zeros, at p=14. It goes through the vertex or point of maximum revenue.
The price for maximum revenue is p = 14 dollars.
Answer:

Step-by-step explanation:
If there are four numbers in a list then the middle 2 numbers should be added up and divided up to give the mean. If we are given the mean we can now work backwards to give us:
(where x and y are the 2 middle numbers)
We can also see that x and y must be equal as the mean is an integer.
So:

So x=43 and that is the middle 2 numbers.
I don't exactly know how to explain how i got the other 2 numbers.
