Answer:
Company A's price per share is $45
Explanation:
The P/E ratio of one company can be used by investors and analysts to determine the value of another companie's stock in the industry. This is called apples-to-apples comparism.
The P/E ratio is used to value a company by comparing its share price to earnings per share.
P/E ratio= market value of shares/ earnings per share
For company B
P/E ratio= 30/2= $15
Using company B's P/E ratio as a benchmark for company A
15= Price per share /3
Price per share = 15*3= $45
