Peter makes a deposit at the end of every three months into a savings account that earns interest at 5.0% compounded semi-annually. He saves for 18 years, and then converts his savings into an annuity that pays him $300 at the beginning of each months for 15 years at the same interest rate. What size of the deposit Peter makes while he is saving?

A trust fund with a beginning balance of $30400 earns interest at 4.6% compounded monthly. If withdrawals of $2060 are made at the beginning of every month, starting 6 years from now, how long will the trust fund last? Round properly. Answer in MONTHS.

A payment of $365 was made at the beginning of each quarter for 8 years into a savings account. After that the accumulated amount was left on the account for 2 years. The interest rate on the account is 3.7% compounded semi-annually. Find the interest earned on the account.

Please don't asnwer if you're not 100% sure about the answer. Thank you!
