Answer:
The company's price–earnings ratio is 36.
Explanation:
Price earning ratio is the ratio of market value of share to earning per share. It shows that how much investors are willing to pay for each dollar of earning of the company.
Profit margin = Net income / sales
0.04 = Net Income / $7800
Net Income = $7800 x 0.04 = $312
Earning Per share = Net Income / number of outstanding shares
Earning Per share = $312 / 6,100 = $0.05
Price earning ratio = Market price of share / Earning per share
