The other machine has a setup cost of $300 and a cost per stamped design of $5. Find the break even point for both stamped designs. \n" ); document.write( "
Algebra.Com's Answer #512304 by JulietG(1812) You can put this solution on YOUR website! For the first machine, the cost is: \n" ); document.write( "720 + 3x \n" ); document.write( "For the second machine, the cost is: \n" ); document.write( "300 + 5x \n" ); document.write( ". \n" ); document.write( "Are they wanting to know when the cost is the same? That's not exactly the \"break even point\". \n" ); document.write( ". \n" ); document.write( "720 + 3x = 300 + 5x \n" ); document.write( "Deduct 3x from each side. \n" ); document.write( "720 = 300 +2x \n" ); document.write( "Subtract 300 from each side. \n" ); document.write( "420 = 2x \n" ); document.write( "Divide each side by 2 \n" ); document.write( "210 = x. \n" ); document.write( ". \n" ); document.write( "The cost is the same for 210 units. Fewer than 210 units and the second option is better. More than 210 units and the first option is better. \n" ); document.write( " |
