the nut house sells walnuts for $4.00 a pound and cashews for $7.00 a pound.how many pounds of cashews should be mixed with 10 pounds of walnuts to obtain a mixture that sells for $5.50 a pound?
\n" ); document.write( "------------
\n" ); document.write( "Let Amt of walnuts be \"x\" lbs; value is 4x dollars
\n" ); document.write( "-------------
\n" ); document.write( "Amt of cashews is \"10-x\" lbs; value is 7(10-x)=70-7x dollars
\n" ); document.write( "---------------
\n" ); document.write( "Amt of mixture = 10 lbs; value = 5.5*10 = 55 dollars
\n" ); document.write( "----------------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "value + value = 55 dollars
\n" ); document.write( "4x + 70-7x = 55
\n" ); document.write( "-3x = -15
\n" ); document.write( "x = 5 (# of lbs of walnuts in the mixture)
\n" ); document.write( "10-x= 5 ($ of lbs of cashes in the mixture)
\n" ); document.write( "--------------
