\n" ); document.write( "

With x being the number of months, and B being the balance after x months, we get the function: B(x) = - 500x + 10,000
\n" );
document.write( "The domain (x) will be from 0 - 20, as he started with 10,000, and with $500 being withdrawn, that $10,000 will be depleted 20 months after. 
\n" );
document.write( "However, since the balance on the credit card is only $3,500, then in this particular case, the DOMAIN (x) will be from 0 - 7. \n" );
