Shereda bought several dozen roses and several dozen carnations.
\n" ); document.write( "The roses cost $15 per dozen, and the carnations cost $8 per dozen.
\n" ); document.write( "Shereda bought a total of 17 dozen flowers and paid a total of $192. How many roses did she buy?
\n" ); document.write( "Equations:
\n" ); document.write( "Quantity Eq: r + c = 17 dozen
\n" ); document.write( "Value Eq:::15r+ 8c = 192 dollars
\n" ); document.write( "---------------------------------------
\n" ); document.write( "Modify:
\n" ); document.write( "8r + 8c = 8*17
\n" ); document.write( "15r+ 8c = 192
\n" ); document.write( "---------
\n" ); document.write( "Subtract and solve for \"r\":
\n" ); document.write( "7r = 56
\n" ); document.write( "r = 8 (# of dozen of roses bought)
\n" ); document.write( "-----
\n" ); document.write( "Solve for \"c\":
\n" ); document.write( "r + c = 17
\n" ); document.write( "8 + c = 17
\n" ); document.write( "c = 9 (# of dozen of carnations bought)
