Answer:
The firm's profit maximization price = $81.25
Step-by-step explanation:
We are given:
Marginal cost MC = $65
Elasticity of demand ED = -5
Therefore, Using the rule of thumb pricing, we have the equation:
![P = (MC)/(1+(1/ED))](https://img.qammunity.org/2021/formulas/business/high-school/3www7uvq980h3uab0ilklg873cumviig56.png)
![P = (65)/(1+(1/-5))](https://img.qammunity.org/2021/formulas/business/high-school/of2bgvqoiuyerufn2pnk6d0ra87fgme4dc.png)
![P = (65)/(0.8)](https://img.qammunity.org/2021/formulas/business/high-school/75cmlrm3xblcpqi8xkw4j0vb35c9bfx8jq.png)
P = $81.25
Therefore the firm's profit maximization price is $81.25
