Answer:
Number of workers = 20.
Step-by-step explanation:
p = - 4w^2 + 160 w
We need to find the value of w when p is a maximum.
We need to convert the equation to vertex form:
p = -4w^2 + 160w
p = -4(x^2 - 40w)
p = -4 [ (x - 20)^2 - 400]
p = -4(x - 20)^2 + 1600.
So the vertex is at (20 , 1600)
The maximum profit is 1600 and the number of workers = 20.
1/4 x 4/7
do the top numbers first. 1 x 4 is 4do bottom numbers next 4 x 7 is 28
that leaves you with 4/28. But you have to reduce.
4/28 = 2/14 = 1/7 (notice I just cut both the top and bottom numbers in half each time I reduced until I couldn't reduce any more).
So, final answer is 1/7

Step-by-step explanation:
I think you might have made a typo, but it would still be 33 if the mean age stays the same.
