The total amount to be repaid by the hotel owner is $30,888.00.
To find the total amount the hotel owner must repay, we need to calculate the interest accrued on the loan.
The formula to calculate the simple interest is: Interest = Principal x Rate x Time.
In this case, the Principal is $30,000.00, the Rate is 12% per year, and the Time is 90 days or 3 months.
First, we convert the time to years by dividing 90 days by 365 (number of days in a year).
So, Time = 90/365 = 0.2466 years.
Now, we can calculate the interest: Interest = $30,000.00 x 0.12 x 0.2466 = $888.
Thus, the total amount that needs to be repaid is the sum of the principal and the interest: $30,000.00 + $888 = $30,888.00.
