Answer:

63 units

Step-by-step explanation:

The profit function P(x) is given by the revenue function minus the cost function:

$P(x) = R(x) - C(x)\\P(x) = 34ln(x+5)-\frac{x}{2}$

The number of units sold 'x' for which the derivate of the profit function is zero, is the number of units that maximizes profit:

$P(x) = 34ln(x+5)-\frac{x}{2}\\P'(x) =0= \frac{34}{x+5}-\frac{1}{2}\\x+5=68\\x=63\ units$

The number of units that should be manufactured so that profit is maximum is 63 units.

OLEGan [10]

Answer:

x+y=9....(i)

2x-6=y....(ii)

then putting the value of y in (i) eqn

x+2x-6=9

3x=15

x=5

Now, putting the value of x in (ii) eqn

then 2*5- 6 =4

Step-by-step explanation:

SO the value of x is 5 and y is 4
