\n" ); document.write( "$14.95 and each Blu-Ray disc cost $16.88 she spent a total of 114.30,
\n" ); document.write( "how many of each did she buy?
\n" ); document.write( "

\r\n" );
document.write( "Let x = the number of DVDs of \"Iron Man\".\r\n" );
document.write( "\r\n" );
document.write( "Then the number of Blu-Ray discs = 7-x\r\n" );
document.write( "\r\n" );
document.write( "Equation:\r\n" );
document.write( "\r\n" );
document.write( "14.95x + 16.88(7-x) = 114.30\r\n" );
document.write( "\r\n" );
document.write( "Solve that for x, the number of DVD's.  Subtract from 7 to find\r\n" );
document.write( "the number of Blu-Ray discs.\r\n" );
