staples sells boxes of pens ($10) and rubber bands($4).
\n" ); document.write( "Leona ordered a total of 24 cartons for $210.
\n" ); document.write( "How many boxes of each did Leona order?
\n" ); document.write( "-----
\n" ); document.write( "Equations:
\n" ); document.write( "Quantity Eq:: p + b = 24 cartons
\n" ); document.write( "Value Eq:: 10p + 4b = 210 dollars
\n" ); document.write( "------------------------------------
\n" ); document.write( "Modify for elimination of the \"p\" terms.
\n" ); document.write( "------
\n" ); document.write( "10p + 10b = 240
\n" ); document.write( "10p + 4b = 210
\n" ); document.write( "-----
\n" ); document.write( "Subtract and solve for \"b\"::
\n" ); document.write( "6b = 30
\n" ); document.write( "b = 5 (# of boxes of bands)
\n" ); document.write( "----
\n" ); document.write( "Solve for \"p\"::
\n" ); document.write( "p + 5 = 24
\n" ); document.write( "p = 19 (# of boxes of pens)
