seed cost .20/oz
\n" ); document.write( "nuts cost .30/oz
\n" ); document.write( "a 42oz mixture costs $11.00
\n" ); document.write( "how many ounces of seeds and nuts were used in this mixture?
\n" ); document.write( "---------------
\n" ); document.write( "Equations:
\n" ); document.write( "Weight Eq.::: s + n = 42 oz
\n" ); document.write( "Value Eq. :: 20s + 30n = 1100 cents
\n" ); document.write( "------------------------------------------
\n" ); document.write( "Multiply the 1st equation by 20 to get:
\n" ); document.write( "20s + 20n = 20*42
\n" ); document.write( "-----
\n" ); document.write( "Subtract that from the Value Eq. and solve for \"n\":
\n" ); document.write( "10n = 1100-840
\n" ); document.write( "10n = 260
\n" ); document.write( "n = 26 oz (# of ounces of nuts needed in the mix)
\n" ); document.write( "----
\n" ); document.write( "since s+n = 42, s = 16 oz (# of ounces of seeds needed in the mix)
\n" ); document.write( "=============================================
