no you dont have to pay

Answer 2

Answer:

No, we don't have to pay the fee after the fourth month.

Step-by-step explanation:

It is given that a bank charges a monthly fee if the average monthly balance of your account is less than $5000.

The table shows the balance of your account the first four months it is open.

Month 1 : $4801.50

Month 2 : $5198.42

Month 3 : $5254.36

Month 4 : $4932.87

Formula for average:

$Average =\frac{\sum x}{n}$

where, n is the number of observation.

The average of four months balance is

$Average =\frac{4801.50+5198.42+5254.36+4932.87}{4}$

$Average =\frac{20187.15}{4}$

$Average =5046.7875$

Since the average balance of 4 months is more than 5000, therefore we don't have to pay the fee after the fourth month.
