Lola, Michael and Joaquin each want to buy a sundae.
\n" ); document.write( "
\r\n" );
document.write( "Let the sundae (one sundae) cost N dollars\r\n" );
document.write( "

\n" ); document.write( "But Lola is 4 dollars short
\n" ); document.write( "
\r\n" );
document.write( "So Lola has N-4 dollars. \r\n" );
document.write( "

\n" ); document.write( "Michael is 3 dollars short,
\n" ); document.write( "
\r\n" );
document.write( "So Michael has N-3 dollars.\r\n" );
document.write( "

\n" ); document.write( "and Joaquin is 1 dollar short.
\n" ); document.write( "
\r\n" );
document.write( "So Joaquin has N-1 dollars\r\n" );
document.write( "

\n" ); document.write( "Combined, they have exactly enough money to buy one sundae.
\n" ); document.write( "
\r\n" );
document.write( "So the sum of the amounts of money they have equals N\r\n" );
document.write( "\r\n" );
document.write( "(N-4)+(N-3)+(N-1) = N\r\n" );
document.write( "      N-4+N-3+N-1 = N\r\n" );
document.write( "             3N-8 = N\r\n" );
document.write( "               2N = 8\r\n" );
document.write( "                N = 4\r\n" );
