\n" ); document.write( " Sonya wants to make a 20-oz mixture of the two types, called Dragon Blend, that will sell for $1.10 an ounce.
\n" ); document.write( ":
\n" ); document.write( "let a = amt of Assam G. tea required
\n" ); document.write( " The total amt is 20 oz, therefore
\n" ); document.write( "(20-a) = amt of Lapsang S.
\n" ); document.write( ":
\n" ); document.write( "A typical mixture equation using cents
\n" ); document.write( "95(20-a) + 143a = 110(20)
\n" ); document.write( "1900 - 95a + 143a = 2200
\n" ); document.write( "-95a + 143a = 2200 - 1900
\n" ); document.write( "48a = 300
\n" ); document.write( "a = 6.25 oz of Assma G. is required
\n" ); document.write( "then
\n" ); document.write( "20 - 6.25 = 13.75 of Lapsang S
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check, find the cost of each
\n" ); document.write( ".95(13.75) = 13.0625
