Algebra.Com's Answer #549696 by Theo(13342)![]() ![]() You can put this solution on YOUR website! if your profit is 30 cents on every dollars that you earn, then your profit is equal to .30 * the number of dollars that you earn.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "your formula is therefore p = .30*x, where x is the number of dollars that you earn.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "what you do is replace what you know in this equation and then solve for what you don't know.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "since you know p = 2740, then replace p in the equation to get:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "2740 = .30*x\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "now you want to solve for x, so you divide both sides of the eqution by .3 to get 2740 / .3 = x\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
