If Ben invests $5000 at 5% interest per year, how much additional money must he invest at 6.5% annual interest to ensure that the interest he receives each year is 5.5% of the total amount invested?
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of additional money he has to invest to accomplish this
\n" ); document.write( ":
\n" ); document.write( "Here is the equation that we want:
\n" ); document.write( ":
\n" ); document.write( "Money invested at 5% + Money invested at 6.5% = Total money at 5.5%
\n" ); document.write( ":
\n" ); document.write( ".05(5000) + .065x = .055(x+5000)
\n" ); document.write( "250 + .065x = .055x + 275
\n" ); document.write( ".065x - .055x = 275 - 250
\n" ); document.write( ".01x = 25
\n" ); document.write( "x = 25/.01
\n" ); document.write( "x = $2500, additional money to be invested
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution using our original equation:
\n" ); document.write( "250 + .065(2500) =
\n" ); document.write( "250 + 162.5 = 412.50
\n" ); document.write( ":
\n" ); document.write( ".055(7500) = 412.50 confirms our solution
\n" ); document.write( ":
\n" ); document.write( "That was pretty easy, right? \n" ); document.write( "
\n" );
