The Board of Directors decided that 1 share is equivalent to $0.50. To calculate how much money is equivalent to 25 shares, we can use the next proportion:
[tex]\frac{1\text{ share}}{25\text{ shares}}=\frac{0.50\text{ \$}}{x\text{ \$}}[/tex]Solving for x:
[tex]\begin{gathered} 1\cdot x=0.50\cdot25 \\ x=12.50\text{ \$} \end{gathered}[/tex]
