\n" ); document.write( "She ordered a total of 500 promotional items and spent ​$210.
\n" ); document.write( "How many of each item did she​ order?
\n" ); document.write( "------
\n" ); document.write( "Equations:
\n" ); document.write( "Quantity:: c + d = 500 items
\n" ); document.write( "Value:: .4c + .5d = 210 dollars
\n" ); document.write( "------------------
\n" ); document.write( "4c + 4d = 2000
\n" ); document.write( "4c + 5d = 2100
\n" ); document.write( "--------------------
\n" ); document.write( "Subtract and solve for \"d\":
\n" ); document.write( "d = 100 (# of date books)
\n" ); document.write( "----
\n" ); document.write( "c = 500 - 100 = 400 (# of calendars)
