How many pounds of candy selling for $1.75 a pound should be added to three pounds of candy selling for $4.25 a pound to create a blend, which will sell for $3.25 a pound?
\n" ); document.write( "

\r\n" );
document.write( "Let x = the number of pounds of the cheaper candy to be mixed\r\n" );
document.write( "Let y = the total number of pounds of candy blend.\r\n" );
document.write( "\r\n" );
document.write( "First you have the AMOUNT OF CANDY equation:\r\n" );
document.write( "\r\n" );
document.write( "+= or x + 3 = y  \r\n" );
document.write( "\r\n" );
document.write( "And second, you have the AMOUNT OF MONEY equation:\r\n" );
document.write( "\r\n" );
document.write( "+= or (x)(1.75) + (3)(4.25) = (y)(3.25) or 1.75x + 12.75 = 3.25y\r\n" );
document.write( "\r\n" );
document.write( "So you have this system of equations:\r\n" );
document.write( "\r\n" );
document.write( "x + 3 = y\r\n" );
document.write( "1.75x + 12.75 = 3.25y\r\n" );
document.write( " \r\n" );
document.write( "\r\n" );
document.write( "Solve that system and get x = 2 and y = 5.\r\n" );
document.write( "\r\n" );
document.write( "Answer: Add 2 pounds of the more expensive candy to end up with \r\n" );
document.write( "5 pounds of candy blend. \r\n" );
