You can put this solution on YOUR website!
all these money type problems are set up the same way once u get used to seeing the pattern then you wont have trouble figuring out what needs to be done
\n" ); document.write( "
\n" );
document.write( "total=$12000
\n" );
document.write( "to get total add both portions x+y
\n" );
document.write( "so
\n" );
document.write( "4%=.04 and 5.5%=.055
\n" );
document.write( "the total interest amount is $532.50
\n" );
document.write( "so
\n" );
document.write( "
\n" );
document.write( "So you have now found your 2 equations to bea ble to solve this problem, once you get used to doing these this process to finding the equations will come naturally.

\n" );
document.write( "\n" );
document.write( "You can solve by elimination or by substitution whichever you find more comfortable using, I like Elimination method as it is much faster.
\n" );
document.write( " multiply by .055
\n" );

\n" );
document.write( "
\n" );
document.write( " subtract equations
\n" );
document.write( "-------------------------
\n" );
document.write( " divide by .015
\n" );
document.write( " this is the portion at 4% interest
\n" );
document.write( "
\n" );
document.write( "Now instead of doing that whole process over to find \"y\" simply plug in the value of \"x\" in the equation
\n" );
document.write( "
\n" );
document.write( " this is the portion at 5.5% interest
