WebJul 9, 2024 · Take the log of both sides. You can take any log you want, but remember that you actually need to solve the equation with this log, so you should use common or natural logs only. Using the common log on both sides gives you log 4 3x –1 = log 11. Use the power rule to drop down the exponent. This step gives you (3 x – 1)log 4 = log 11. WebPV = $125,000 / 0.045 PV. = $2,777,777.78. Therefore, the lottery is worth $2,777,778 today if the interest rate is 4.5% per year. The answer is C) $2,777,778. 8) We can use the formula for the future value of a present sum compounded annually: FV = PV x (1 + r)^n. where FV is the future value, PV is the present value,
