You can put this solution on YOUR website!
Let: I= initial M= Monthly
\n" ); document.write( "System:
\n" ); document.write( "I+5M=225
\n" ); document.write( "I+10M=375
\n" ); document.write( "==========
\n" ); document.write( "I=225-5M
\n" ); document.write( "(225-5M)+10M=375
\n" ); document.write( "225+5M=375
\n" ); document.write( "5M=150
\n" ); document.write( "M=30
\n" ); document.write( "I=225-5x30=75
\n" ); document.write( "Ans:I=$75, M=$30\r
