$\"p\"$ = number of pennies
\n" ); document.write( " $\"n\"$ = number of nickels
\n" ); document.write( "given:

\n" ); document.write( "(2) $\"1%2Ap+%2B+5%2An+=+1450\"$ (in cents)
\n" ); document.write( "subtract (1) from (2)
\n" ); document.write( "(2) $\"1%2Ap+%2B+5%2An+=+1450%7D%7D%0D%0A%281%29+%7B%7B%7B-p+-+n+=+-450\"$
\n" ); document.write( " $\"4n+=+1000\"$
\n" ); document.write( " $\"n+=+250\"$
\n" ); document.write( "and, since
\n" ); document.write( " $\"p+%2B+n+=+450\"$
