$\"C%5B1%5D=2%2B0.50N\"$ , $\"N%3E=9\"$
\n" ); document.write( " $\"C%5B2%5D=7\"$
\n" ); document.write( "So find $\"N\"$ ,
\n" ); document.write( " $\"C%5B1%5D=C%5B2%5D\"$ \r

\n" ); document.write( " $\"0.5N=5\"$
\n" ); document.write( " $\"N=10\"$
\n" ); document.write( "At 10 checks (plus the original 8 free checks), the costs would be the same.
\n" ); document.write( "So to keep it less than the second account, you could write at most 17 checks.\r
