Algebra.Com's Answer #197661 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! Let x = the number of lbs. of hazelnuts at $6.50 per pound and (60-x) = the number of lbs. of cashews at $4.50 per pound. \n" ); document.write( "The mixture (the sum of these two) is to be 60 lbs at $5.10 per pound. \n" ); document.write( "This can be expressed algebraically by: \n" ); document.write( "6.5x+4.5(60-x) = 5.1(60) Simplify. \n" ); document.write( "6.5x+270-4.5x = 306 Combine like-terms. \n" ); document.write( "2x+270 = 306 Subtract 270 from both sides. \n" ); document.write( "2x = 36 Divide both sides by 2. \n" ); document.write( "x = 18 \n" ); document.write( "Jackie will need to mix 18 lbs. of hazelnuts @ $6.50 per pound with (60-18 = 42)lbs. of cashews @ $4.50 per pound to obtain 60 pounds of the mixture @ $5.10 per pound. \n" ); document.write( " |
