A couple wants to accumulate $10 000 by December 31, 2023. They make 10 annual deposits starting January 1, 2014. If interest is at j1 = 2%, what annual deposits are needed?

Deposits of $350 are made every 3 months from June 1, 2014, to June 1, 2017. How much has been accumulated on September 1, 2017, if the deposits earn j4 = 6%?

Melissa takes her inheritance of $25 000 and invests it at j12 = 6%. How many monthly payments of $250 can she expect to receive and what will be the size of the concluding payment?

A loan of $10 000 is to be repaid by monthly payments of $400, the first payment due in one year's time. If j12 = 12%, determine the number of regular monthly payments needed and the size of the final smaller payment.
