\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let rate that $5,000 ($15,000 – 10,000) need to be invested at, be r
\n" ); document.write( "Then: .12(10,000) + r(5,000) ≥ 2,200
\n" ); document.write( "1,200 + 5,000r ≥ 2,200
\n" ); document.write( "5,000r ≥ 2,200 – 1,200
\n" ); document.write( "5,000r ≥ 1,000\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "r, or rate to invest $5,000 ≥ \"1000%2F5000\", or \"highlight_green%28r+%3E=+20%29\"% \r
\n" ); document.write( "\n" ); document.write( "OR\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "$5,000 need to be invested at a certain rate in order to make $1,000 ($2,200 - 1,200). This is then written as: r(5,000) ≥ 1,000. Solve for r and the rate is found.\r
