# (a) Graph the marginal profit function for the profit function P ( x )   =   16 x − 0.1 x 2 —   100 , where P ( x ) is in hundreds of dollars and x is hundreds of units.(b) What level of production and sales will give a 0 marginal profit?(c) At what level of production and sales will profit be at a maximum?(d) What is the maximum profit?

(a)

To determine

To graph: The marginal profit function for the profit function P(x)=16x0.1x2100 where P(x) is in hundreds of dollars and x is hundreds of units.

Explanation

Given Information:

The provided profit function is P(x)=16x0.1x2100 where P(x) is in hundreds of dollars and x is hundreds of units.

Graph:

Consider the provided profit function, P(x)=16x0.1x2100

It is known that if P=P(x) is the profit function for a product, then the marginal profit function is MP¯=P(x).

So, if the profit function is P(x)=16x0.1x2100, then the marginal profit function is,

P(x)=160.1(2x)=160.2x

Now, draw the graph of P(x)=160.2x by

Choose some values for x and compute the value for P(x), in order to form the ordered pairs.

Put x=0 in the function P(x)=160.2x.

P(x)=160.2x=160.2(0)=16

Put x=30 in the function P(x)=160.2x.

P(x)=160

(b)

To determine

To calculate: The level of production and sales that give a zero-marginal profit.

(c)

To determine

To calculate: The level of production and sales at which the profit will be maximum.

(d)

To determine

To calculate: The maximum profit for the profit function P(x)=16x0.1x2100 where P(x) is in hundreds of dollars and x is hundreds of units.
