Answer:
Step-by-step explanation:
Given that:
R(x) =
+ 34x − 17
As we know that derivative of revenue function is marginal revenue function .
We will use following rules of derivative
=> dR/ dx =
=> R' (x) =
=> R '(2000) =
= 34
The revenue when 2000 units are sold is:
R(2000) =
+ 34*2000 − 17 = $69,783
4.4354 rounded to 2 decimal places is 4.44
X+y=31.5
x-y=5.25
add 2 equations
x+y+x-y=31.5+5.25
2x=36.75
x=18.375
y=31.5-18.375=13.125
check : 18.375+13.125=31.5, 18.375-13.125=5.25
so
Answer:
18.375 and 13.125
