\n" ); document.write( "Let \"x%2B10\" be = to overtime hrs that Jerry worked
\n" ); document.write( "and \"x\" = to overtime hrs that Andrew worked\r
\n" ); document.write( "\n" ); document.write( "=> ratio is \"%28x%2B10%29%2Fx\"\r
\n" ); document.write( "\n" ); document.write( "If Jerry worked \"4\" overtime hours for every \"3\" hours that Andrew worked, ratio is \"4%2F3\" and we have\r
\n" ); document.write( "\n" ); document.write( "since ratios must be same,we have
\n" ); document.write( "
\n" ); document.write( "\"%28x%2B10%29%2Fx=4%2F3\" .......cross multiply\r
\n" ); document.write( "\n" ); document.write( "\"4x=3%28x%2B10%29\"\r
\n" ); document.write( "\n" ); document.write( "\"4x=3x%2B30\"\r
\n" ); document.write( "\n" ); document.write( "\"4x-3x=30\"\r
\n" ); document.write( "\n" ); document.write( "\"x=30\"\r
\n" ); document.write( "\n" ); document.write( " -> so, Jerry worked \"x%2B10+=30%2B10=40\" overtime hrs
\n" ); document.write( "-> \"x=30\" ->Andrew worked 30 overtime hrs\r
\n" ); document.write( "\n" ); document.write( "check:\r
\n" ); document.write( "\n" ); document.write( "\"%28x%2B10%29%2Fx=4%2F3\"\r
\n" ); document.write( "\n" ); document.write( "\"%2830%2B10%29%2F30=4%2F3\"\r
\n" ); document.write( "\n" ); document.write( "\"40%2F30=4%2F3\"...simplify left side\r
\n" ); document.write( "\n" ); document.write( "\"4%2F3=4%2F3\"\r
