Companies such as greaterthanorequalto that have huge amounts of cash flow every day base their financial calculations on continuous compounding lf the company wants to make an effective 25% per year, compounded continuously, what nominal daily rate of return has to be realized? Assume 365 days per year. A small company plans to spend $10.000 in year 2 and $10,000 in scar 5 At an interest rate of effective 10% per year, compounded semiannually the equation shat represents the equivalent annual worth A in years 1 through 5 is A = 10,000(PIF, 10%, 2)(AIP, 10%, 5) + 10.000(A_IF, 10%, 5) A = 10,000(AIP, 10%, 4) + 10.000(A_F, 10%, 5) A = 10,000(PIF, 5%, 2)(AIP, 5%, 10) + 10.000(A_IF, 5%, 10) A = 10,000(PIP, 10%, 5) + 10.000](AIF, 10%, 5) Assume you make monthly deposits of $200 starting one month from now into an account that pays 6% per year, compounded semiannually If you want to know the total after 4 years, the value of n you should use in the FIA factor is 2 4 8 12 An engineer who is saving for her retirement plans to deposit $500 every quarter, starting one quarter from now, into an investment account.
