A. John and Riku have jobs and contribute to the household expenses according to their income. John contributes 75% of the expenses, and Riku contributes 25%. Currently, their household expenses are $30,000 annually (hint, assume payments at the beginning of the year, i.e., BEG mode). John and Riku have three children. The youngest child is 12, so they would like to ensure that they could maintain their current standard of living for at least the next eight years. They feel that the insurance proceeds could be invested at five percent. In addition, to covering the annual expenses, they would like to make sure that each of their children has $30,000 available for college. If John was to die, Riku would go back to school part time to upgrade her training as a nurse. This would cost $28,500. They have a mortgage on their home with a balance of $175,000.
