Hi
\n" ); document.write( "stock B cost twice as much as stock A , but the profit on B was only 3/4 as much as on A when both were sold.\r
\n" ); document.write( "\n" ); document.write( "what was the cost of each stock if;
\n" ); document.write( "a)the total cost was $3000.00
\n" ); document.write( "b)the total selling price $2,700 resulted in an average 20% profit on the cost.\r
\n" ); document.write( "\n" ); document.write( "thanks
\n" ); document.write( "

a)  Let cost of stock A be A
\n" );
document.write( "    Then cost of stock B = 2A
\n" );
document.write( "    We then get: A + 2A = 3,000____3A = 3,000
\n" );
document.write( "    A, or 
\n" );
document.write( "    \r
\n" );
document.write( "\n" );
document.write( "b)  2,700 = 1.2C, since selling price ($2,700) was 20% more than the combined cost 
\n" );
document.write( "    C, or cost of both = 
\n" );
document.write( "    Let cost of stock A be A
\n" );
document.write( "    Then cost of stock B = 2A
\n" );
document.write( "    We then get: A + 2A = 2,250____3A = 2,250
\n" );
document.write( "    A, or 
\n" );
document.write( "    
\n" );
document.write( "I don't see any use for this statement: \"but the profit on B was only 3/4 as much as on A when both were sold,\" unless I misunderstood or misread the problem. \n" );
document.write( "

\n" );
