if all the retained earnings represent earnings in the current year and dividends are paid from current earnings...

0.28 ret. earn. + 0.01 div. pd = 0.29 earnings per share

P/E = 322.74 / 0.29 = 1,112.90

Div yield = 0.01 / 322.74 = 0.000031, or 0.000031 * 100 = 0.0031%

stock of amazon is selling at 322.74 per share and it has retained earning of $0.28 per share, and dividends of $0.1 per share.

a) what is the EARNING OF A SHARE

b) what is the PRICE-EARNING RATIO

c) what is the DIVIDEND YIELD

thanks!
