TRY IT YOURSELF example question

On January 1, 2021 you borrow a $15,000 loan from the bank with a 7.5% accrued interest. If you do not plan on making any payments during the loan period, find the total balance of your loan, in dollars, that you will owe to the bank on January 1, 2022 for

a)  Daily compounded interest

b)  Weekly compounded interest

c)  Monthly compounded interest
