Let's begin by listing out the information given to us:
Number of shares (n) = 3.5 million shares
Share price (p) = $57 per share
Company earnings (E) = $10.5 million
We are to calculate PE ratio
[tex]\begin{gathered} PE(Ratio)=\frac{\text{Price per Share}}{\text{Earning per Share}} \\ PE(Ratio)=\frac{n\cdot p}{E}=\frac{3.5\cdot10^6\cdot57}{10.5\cdot10^6}=19 \\ PE(Ratio)=19.00(2\text{ decimal places)} \end{gathered}[/tex]
