Can someone help me to solve both problems? Problem 1: uses payments and problem 2 uses time

= = 1. Determine the discounted value of a series of 20 annual payments of $500 if i(l) = 5% and we want to allow for an inflation factor of i(1) 2%. (Assume the payments are at the end of each year and the first payment is $500.) 2. A court is trying to determine the discounted value of the future income of a man paralyzed in a car accident. At the time of the accident the man was earning $45 000 a year and anticipated getting a 4% raise each year. He is 30 years away from retirement. If money is worth (1) = 5%, what is the discounted value of his future income? (Assume payments are at the end of each year and the first payment is $45 000(1.04) = $46 800.) =
