Jill wants to mix almonds and peanuts so that the retail price will be $4.90 per pound.
\n" ); document.write( " Almonds cost $7 per pound, and peanuts cost $3 per pound.
\n" ); document.write( " She wants to add 20% to the base price for her own profit, after which she will have the final retail price.
\n" ); document.write( " In what percentage ratio should she mix the almonds and the peanuts?
\n" ); document.write( ":
\n" ); document.write( "Assuming the the final retail price will be 1.2*4.90 = $5.88 a pound including the 20% profit
\n" ); document.write( ":
\n" ); document.write( "Assume there is a mix of 10 lb
\n" ); document.write( ":
\n" ); document.write( "Let x = amt of Almonds
\n" ); document.write( "then
\n" ); document.write( "(10-x) = amt of peanuts
\n" ); document.write( ":
\n" ); document.write( "3(10-x) + 7x = 5.88(10)

\n" ); document.write( "4x = 28.8
\n" ); document.write( "x = 28.8/4
\n" ); document.write( "x = 7.2 lb of almonds
