You can put this solution on YOUR website!
Let number of pounds of Raisins = R
\n" ); document.write( "Number of pounds of Pineapple = P
\n" ); document.write( "Total weight of mixture = 20
\n" ); document.write( "P+R = 20\r
\n" ); document.write( "\n" ); document.write( "price per pound of raisins = 3
\n" ); document.write( "Total price of raisins = 3 X R = 3R
\n" ); document.write( "Price per pound of pineapple = 4
\n" ); document.write( "Total price of Pineapple = 4 X P = 4P\r
\n" ); document.write( "\n" ); document.write( "We are making 20pounds of mixture worth 3.60 per pound
\n" ); document.write( "SO total price of the mixture = 20 x 3.6 = 72\r
\n" ); document.write( "\n" ); document.write( "So 3R + 4P = 72
\n" ); document.write( " R + P = 20\r
\n" ); document.write( "\n" ); document.write( "Can you solve from here?
