and then use the formula for principal.
The principal is $104,000.
Check the answer using I = PRT. The principal is $104,000, the rate is 10%, and the time is
year. The interest should be, and is, $780.
The calculator approach to finding the principal uses parentheses so that the numerator is divided by the entire denominator.
