Tori invested $8000 in money market funds. Part was invested at 5% simple interest, and the rest was invested at 7% simple interest. At the end of 1 year. Tori had earned $496 in interest. How much did she invest in each fund?\r
\n" ); document.write( "\n" ); document.write( "Let the amount invested in 5% funds be x
\n" ); document.write( "Then 8000-x will be invested in 7% funds\r
\n" ); document.write( "\n" ); document.write( "5% ------------------------- 7%--------------------- interest\r
\n" ); document.write( "\n" ); document.write( "x-------------------------8000-x----------------------496\r
\n" ); document.write( "\n" ); document.write( ".05x+.07(8000-x)=496\r
\n" ); document.write( "\n" ); document.write( "0.05x+560-0.07x = 496
\n" ); document.write( "-0.02x=-560+496
\n" ); document.write( "-0.02x= -64
\n" ); document.write( "x= -64/-0.02
\n" ); document.write( "x=3200\r
