The Eastside Nursery ordered 27 trees. Some of the trees were elms, costing $17 each. The remainder was maples at $11 each. The total cost of the trees was $375. Find the number of elms and the number of maples.

\n" ); document.write( "Equations:
\n" ); document.write( "e + m = 27
\n" ); document.write( "17e+11m = 375
\n" ); document.write( "---
\n" ); document.write( "Multiply thru the 1st equation by 17:
\n" ); document.write( "17e + 17m = 17*27
\n" ); document.write( "17e + 11m = 375
\n" ); document.write( "----
\n" ); document.write( "Subtract and solve for \"m\":
\n" ); document.write( "6m = 84
\n" ); document.write( "m = 14 (# of maple trees purchased)
