A store buys granola at $1/lb and dried fruit at $2/lb. and sells them at 25% markup. The store sells 2 special mixtures of granola and dried fruit. One customer buys 6 lbs. of Mixture A and 4 lbs of Mixture B and pays $17. Another custoemr reverses the proportions and pays a dollar more. \r
\n" ); document.write( "\n" ); document.write( "Given:
\n" ); document.write( "Selling Prices
\n" ); document.write( "Granola : $1 plus 25% mark-up = $1.25/lb
\n" ); document.write( "Dried Fruit : $2 plus 25% mark-up = $2.50/lb\r
\n" ); document.write( "\n" ); document.write( "Let A = Selling price of mixture A
\n" ); document.write( " B = Selling price of mixture B\r
\n" ); document.write( "\n" ); document.write( "Equation 1
\n" ); document.write( "6A + 4B = 17\r
\n" ); document.write( "\n" ); document.write( "Equation 2
\n" ); document.write( "4A + 6B = 18
\n" ); document.write( "multiply equation 2 by 1.5
\n" ); document.write( "6A + 9B = 27
\n" ); document.write( "deduct equation 2 by equation 1\r
\n" ); document.write( "\n" ); document.write( "(6A-6A)+ (9B-4B) = 27 -17
\n" ); document.write( " 5B = 10
\n" ); document.write( " B = 2\r
\n" ); document.write( "\n" ); document.write( "substitute B=2 in equation1
\n" ); document.write( "6A + 4(2) = 17
\n" ); document.write( " 6A = 17-8
\n" ); document.write( " A = 1.5\r
\n" ); document.write( "\n" ); document.write( "If mixtures A & B is sold at Granola = $1 plus 25% mark-up = $1.25/lb
\n" ); document.write( "& $2.00/lb respectively, we ca now compute the recipe for mixtures A & B\r
\n" ); document.write( "\n" ); document.write( "Given
\n" ); document.write( "Selling prices
\n" ); document.write( "Mixture A = $1.50/lb
\n" ); document.write( "Mixture B = $2.00/lb\r
\n" ); document.write( "\n" ); document.write( "Let x = % of Granola in mixture A
\n" ); document.write( "1.25x + 2.5(1-x) = 1.5
\n" ); document.write( " x = 80%
\n" ); document.write( "So recipe for mixture A is 80% Granola & 20% Dried Fruit\r
\n" ); document.write( "\n" ); document.write( "Let y = % 0f Granola in mixture B
\n" ); document.write( "1.25 y + 2.5(1-y) = 2
\n" ); document.write( " y = 40%
\n" ); document.write( "So recipe for mixture B is 40% Granola & 60% Dried Fruit\r
\n" ); document.write( "
\n" ); document.write( "
