A deposit of $4000 is made into an account that earns 11% annual simple interest.
\n" ); document.write( " How much additional money must be deposited into an account that pays 14% annual simple interest so that the total interest earned is 12% of the total investment?
\n" ); document.write( ":
\n" ); document.write( "let x = amt of additional money at 14%, required to do this
\n" ); document.write( "then
\n" ); document.write( "(x+4000) = the total investment
\n" ); document.write( ":
\n" ); document.write( "write an equation using the decimal equiv of per cent
\n" ); document.write( ".11(4000) + .14x = .12(x+4000)
\n" ); document.write( "440 + .14x = .12x + 480
\n" ); document.write( ".14x - .12x = 480 - 440
\n" ); document.write( ".02x = 40
\n" ); document.write( "x = 40/.02
\n" ); document.write( "x = $2000 addition at 14%
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "You can check this for yourself, replace x with 2000 in the original equation
\n" ); document.write( " \n" ); document.write( "

\n" );
