Do the relevant calculations so you can indicate which you prefer a bank account that pays 5.8% per year (EAR) for 3 years or a. an account that pays 2.7% every 6 months for 3 years? b. an account that pays 6.6% every 18 months for 3 years? c. an account that pays 0.54% per month for 3 years? (Note: Compare your current bank EAR with each of the three alternative accounts. Be careful not to round any intermediate steps less than six decimal places.)
