You can put this solution on YOUR website!
Let \"+p+\" = the normal price of 1 cookie
\n" ); document.write( "in cents
\n" ); document.write( "---------------
\n" ); document.write( "Today's price for 1 cookie:
\n" ); document.write( "\"+p+-+75+\" cents
\n" ); document.write( "-----------------
\n" ); document.write( "The price of 7 cookies today:
\n" ); document.write( "\"+7%2A%28+p+-+75+%29+\" cents
\n" ); document.write( "--------------------------
\n" ); document.write( "\"+7%2A%28+p+-+75+%29+=+280+\" ( in terms of cents )
\n" ); document.write( "\"+7p+-+525+=+280+\"
\n" ); document.write( "\"+7p+=+805+\"
\n" ); document.write( "\"+p+=+115+\" cents
\n" ); document.write( "The normal price of 1 cookie is $1.15
\n" ); document.write( "------------
\n" ); document.write( "check:
\n" ); document.write( "\"+7%2A%28+115+-+75+%29+=+280+\"
\n" ); document.write( "\"+7%2A40+=+280+\"
\n" ); document.write( "\"+280+=+280+\"
\n" ); document.write( "OK
\n" ); document.write( "
\n" ); document.write( "
