\n" ); document.write( ":
\n" ); document.write( "We can use proportion here, let x = amt when int rate is 4.2
\n" ); document.write( ":
\n" ); document.write( "\"4.5%2F4.2\" = \"60%2Fx\"
\n" ); document.write( "Cross multiply
\n" ); document.write( "4.5x = 4.2* 60
\n" ); document.write( "4.5x = 252
\n" ); document.write( "x = \"252%2F4.5\"
\n" ); document.write( "x = $56
