Hello. It appears as if you forgot to include the \"/3\" with the 152 + x≥80. It should read as\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28152%2Bx%29%2F3%3E=80\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Next, multiply 3 to both sides of the inequality, giving us:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "152 + x ≥ 240\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Subtract 152 from both sides, which will give us the range of scores:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x ≥ 88
\n" ); document.write( "
\n" );
