Question

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 Noah's account has gone into overdraft. His balance is $-27-79. T
get back to a positive balance, he plans to deposit money at a steady rate of
$39-91 per week. How much will be in his account after 6 weeks?

Answer 1

The balance when the account went into overdraft was -38.02

Explanation:

Let x be the balance when the account went into overdraft

To get back to a positive balance he deposited money at a steady rate of $20.06 per week.

Amount deposited per week = $20.06

Amount deposited 8 weeks =

Now amount in account after 8 weeks =x+160.48

We are given that After 8 weeks, he had $122.46 in the account.

So,x+160.48=122.46

x=122.46-160.48

x=-38.02

Hence The balance when the account went into overdraft was -38.02

Answer 2

$211.67

Explanation:

Each week for six weeks, Noah deposited $39.91, which means he deposited $39.91 six times in his bank account.

So amount he deposited = 239.46 - (-27.79) = 211.67
