Answer:
To find the total amount required to repay the loan, we need to calculate the total amount including both the borrowed amount and the interest.
First, let's find the amount of interest Tony needs to pay:
Interest = Principal * Rate * Time
Substituting the given values:
Interest = $6800 * 0.06 * (9/12) = $306
Now, let's add the interest to the borrowed amount to find the total repayment amount:
Total repayment amount = Borrowed amount + Interest
Total repayment amount = $6800 + $306 = $7106
So, the total amount required to repay the loan is $7106.
