The profit, y, is to be at least $4000.00 or, algebraically, $\"y+%3E=+4000\"$ , but y = 0.02x-0.30, so substitute this into the above inequality to get:
\n" ); document.write( " $\"0.02x-0.30+%3E=+4000\"$ Solve for x. Add 0.30 to both sides.
\n" ); document.write( " $\"0.02x+%3E=+4000.30\"$ Now divide both sides by 0.02
\n" ); document.write( " $\"x+%3E=+200015\"$
\n" ); document.write( "So at least 200,015 items must be sold to earn a profit of at least $4,000.00
