To set up this word problem,it's good to start writing out what we know:
\n" ); document.write( "We know George has two investments (let's call them x & y), one at 6% and the other at 8%.
\n" ); document.write( "The two investments yield a total of $185.60 in annual interest.
\n" ); document.write( "So, 0.06x+0.08y=185.60
\n" ); document.write( "Next:
\n" ); document.write( "We know the amount invested at 8% is $320 less than twice the amount invested at 6% which means: y=2x-320.
\n" ); document.write( "So that leaves us with: 0.06x+0.08y=185.60 and y=2x-320
\n" ); document.write( "Use the substitution method to continue solving. I hope this helps you out!
\n" ); document.write( " \n" ); document.write( "

\n" );
