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. Taylor's account
has gone into overdraft. Her balance is $-23.34. To get back to a positive balance, she
plans to deposit money at a steady rate of $27.24 per week. How much will be in her
account after 7 weeks?
