Call w the number of weeks it will take her...thus she saves 7 dollars each week...so we write
\n" ); document.write( "42 + 7w = 133
\n" ); document.write( "Subtract 42 and get
\n" ); document.write( "7w = 91
\n" ); document.write( "Divide by 7 and get
\n" ); document.write( "w = 13 weeks
\n" ); document.write( "
\n" );
