Are you confused yet by what the other person did? If so, read on!
\n" ); document.write( "Let the number of quarters be Q
\n" ); document.write( "Then number of dimes = 2.5Q
\n" ); document.write( "We then get: .1D + .25Q = 16
\n" ); document.write( ".1(2.5Q) + .25Q = 16 ----- Substituting 2.5Q for D
\n" ); document.write( "Continue to solve for Q, the number of quarters, and you should get \"highlight_green%28matrix%281%2C3%2C+32%2C+of%2C+them%29%29\" \n" ); document.write( "
\n" );
