Answer:
the charge for opening up the account was $155.
Explanation:
To find the charge for opening up the account, we need to subtract the interest from the total amount borrowed.
The total amount repaid at the end of the loan period is the sum of the amount borrowed and the interest charged. In this case, the total amount repaid is:
$2,500 + $155 = $2,655
The interest charged on the loan is the difference between the total amount repaid and the amount borrowed. Therefore, the amount charged for opening up the account is:
$2,655 - $2,500 = $155
So the charge for opening up the account was $155.
