You can put this solution on YOUR website!
material = 22.50 per chair.
\n" ); document.write( "advertising = 420.
\n" ); document.write( "let x = the number of chairs.
\n" ); document.write( "revenue = 75 * x
\n" ); document.write( "cost = 420 + 22.50 per chair.
\n" ); document.write( "break even is when the cost is equal to the revenue.
\n" ); document.write( "your equation is:
\n" ); document.write( "75 * x = 420 + 22.50 * x
\n" ); document.write( "subtract 22.50 * x from both sides of the equation to get:
\n" ); document.write( "75 * x - 22.50 * x = 420
\n" ); document.write( "combine like terms to get:
\n" ); document.write( "52.50 * x = 420
\n" ); document.write( "divide both sides of the equation by x to get:
\n" ); document.write( "420 / 52.50 = x
\n" ); document.write( "solve for x to get:
\n" ); document.write( "x = 8
\n" ); document.write( "carpenter needs to esll 8 chairs to break evn.
\n" ); document.write( "revenue = 75 * 8 = 600
\n" ); document.write( "cost = 420 + 22.50 * 8 = 600
\n" ); document.write( "the break even point is when the revenue = 600 and the cost = 600.
\n" ); document.write( "that occurs when the number of chairs sold is 8.
\n" ); document.write( " \n" ); document.write( "
\n" );
