Let's find out the cost of labor shall we...
$8 x 40 x 2 = $640
--------
Now let's answer your question...
($640)/($2000) = 0.32
---------
This means that the cost of labor would be equal to 32% of the revenue as 0.32 = 32/100.
I) Q = 7*P
ii) Q = 35
iiI) 42 = 7*P
42 / 7 = P
so P = 6
The answer is -x/2-8x^2-16/x^2-9.
Hope this helped.
No, because to half something you have to divide by 2 or multiply by .5
