A total of $10,000 is invested in two funds paying 5% and 7% annual interest. The combined annual interest is $630. How much of the $10,000 is invested in each fund?
\n" ); document.write( "----
\n" ); document.write( "Equation:
\n" ); document.write( "interest + interest = 630
\n" ); document.write( "0.05x + 0.07(10,000-x) = 630
\n" ); document.write( "----
\n" ); document.write( "Multiply thru by 100 and solve for \"x\":
\n" ); document.write( "5x + 7*10,000 - 7x = 63000
\n" ); document.write( "-2x = -7000
\n" ); document.write( "x = $3500 (amt. invested at 5%)
\n" ); document.write( "10,000-x = $6500 (amt. invested at 7%)
\n" ); document.write( "==========================================
