The interest rate is 7% per year compounded semi annually. You account for your company's profits on a weekly basis. What is the effective rate to be used in using the time value of money equations to find the present or future value of an annuity? (Hint: CP and PP, 4 weeks in a month, 30 days in month, 26 weeks in 6 months, 52 weeks in a year)(Note: no units, the answer should be in decimals such that 10% is actually 0.1000, use 4 decimal points, threshold is 0.0001) Answer Google expects its ad revenue to increase by 3% per year, if last year they made $17073billion, what is the present value of its ad business assuming an MARR of 6%? (note put the answer in billions such that 10,000,000,000 is just 10.0000, no units, use 4 decimals, tolerance 5%, assume the company does not go bankrupt :))
