Many bank accounts never go below zero. But some banks will allow a negative balance, at least for a short time, called an overdraft. It means someone has taken

out, or 'drafted', more money than was in the account to begin with. Kylie's account

went into overdraft. To get back to a positive balance, she deposited money at a

steady rate of $23.38 per week. After 6 weeks, she had $109.87 in the account. What

was the balance when the account went into overdraft?
