First you know that Jessica bought the stock for $32 per share: 32x = y (where y is the total amount she paid for the stock).
\n" ); document.write( "Next you know that she sold the stock (same amount) for $56 per share: 56x = z (where z is the total amount she made from the sale).
\n" ); document.write( "Finally you know that she made a profit of $552, so the difference between what she sold it for and what she paid for it should be 552: z - y = 552
\n" ); document.write( "Now plug the first two equations into the third and solve for x:
\n" ); document.write( "z - y = 552
\n" ); document.write( "56x - 32x = 552
\n" ); document.write( "24x = 552
\n" ); document.write( "x = 23
\n" ); document.write( "So she bought 23 shares of stock. \n" ); document.write( "

\n" );
