You can put this solution on YOUR website!
Let x = the number of books to be sold at $1.15 per copy.
\n" ); document.write( "Now the problem says \"...the author wants to earn at least $46,000\" So this means that you need to write an inequality rather than an equation.
\n" ); document.write( "In writing inequalities, \"a is at least = to b\" is expressed as $\"a%3E=b\"$ (a is greater than or equal to b), so you would write:
\n" ); document.write( " $\"%281.15%29x+%3E=+46000\"$ Now you can solve inequalitites much like you would solve equations.
\n" ); document.write( " $\"%281.15%29x+%3E=+46000\"$ Divide both sides by 1.15
\n" ); document.write( " $\"x%3E=40000\"$
\n" ); document.write( "So the author must sell at least 40,000 copies to earn at least $46,000 \n" ); document.write( "

\n" );
