Algebra.Com's Answer #464521 by josgarithmetic(39617)![]() ![]() ![]() You can put this solution on YOUR website! What would be the price of the mixture of these teas, if u= kg of P24 type and v = kg of the P34 type: \n" ); document.write( " \n" ); document.write( "The 1 kg unit cost is \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Undo that 20% profit to know the cost per kg for the mixture originally. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Original mixture price: \n" ); document.write( "And we could have assumed the original mixing were based on forming a 1 kilogram mixture, so that \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Use that sum relationship as substitution to the \"30\" equation and divide left & right by 2 to simplify that \"30\" so you have this system to solve:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Now just solve for u and v. \n" ); document.write( " |
