Expert Solution
Step 1

Consider the given cost function as Cx=16000+120x-0.022x2 and the price quantity relationship as p=520-320x.

a) The revenue function is denoted by Rx and is defined by the formula Rx=px.

Substitute p=520-320x in Rx=px as shown below.

Rx=520-320xx=520x-320x2

Hence, the revenue function is Rx=520x-320x2.

The profit function is denoted by Px and is defined by the formula Px=Rx-Cx.

Substitute Rx=520x-320x2 and Cx=16000+120x-0.022x2 in Px=Rx-Cx as shown below.

Px=Rx-Cx=520x-320x2-16000+120x-0.022x2=520x-320x2-16000-120x+0.022x2=-320+0.022x2+520-120x-16000=-0.128x2+400x-16000

Hence, the profit function is Px=-0.128x2+400x-16000.
