You borrowed $30,000 to finance the education expenses for your senior year of college at the beginning of your senior year. The loan will be paid off over five years and the first installment will be due a year later. The loan carriers an interest rate of 7% per year and is to be repaid in equal annual installments over the next five years. Suppose you want to negotiate with the bank to defer the first loan installment until the end of year 2. (But you still desire to make five equal installments at 7% interest.) If the bank wishes to earn the same profit, what should be the new annual installment

You are the manager of a large crude-oil refinery. as part of the refining process, a certain heat exchanger (operated at high temperatures and with abrasive material flowing through it) must be replaced every year. the replacement and downtime cost in the first year is $165 comma 000. this cost is expected to increase due to inflation at a rate of 7% per year for six years (i. e. until the eoy 7), at which time this particular heat exchanger will no longer be needed. if the company's cost of capital is 15% per year, how much could you afford to spend for a higher quality heat exchanger so that these annual replacement and downtime costs could be eliminated?
