You can put this solution on YOUR website!
Your calculations are correct.\r
\n" ); document.write( "\n" ); document.write( "The amount invested at 7% is $9000
\n" ); document.write( "The amount invested at 5% is $4500.\r
\n" ); document.write( "\n" ); document.write( "This statement is wrong : .05(13,500 - 9000)=4500
\n" ); document.write( "It should be 0.05*(13500-9000) = 225\r
\n" ); document.write( "\n" ); document.write( "If that is the reason your instructor is rejecting your answer, I feel for you. It will be a really long year in a classroom with a nit picker like that :(
