\n" ); document.write( "Equations:
\n" ); document.write( "Quantity:: d = 3.5q
\n" ); document.write( "Value:::: 10d + 25q = 1560 cents
\n" ); document.write( "--------------------------------------
\n" ); document.write( "Substitute for \"d\" and solve for \"q\"::
\n" ); document.write( "10*3.5q + 25q = 1560
\n" ); document.write( "35q + 25q = 1560
\n" ); document.write( "60q = 1560
\n" ); document.write( "q = 26 (# of quarters)
\n" ); document.write( "---
\n" ); document.write( "solve for \"d\"
\n" ); document.write( "d = 3.5q
\n" ); document.write( "d = 3.5*26 = 91 (# of dimes)
