May I ask: Jeff just hit the jackpot in Las Vegas and won $25,000. If he invests it now at 12% interest rate, how much will it be worth in 20 years?

Evan would like to have $2,000,000 saved by the time he retires in 40 years. How much does he

need to invest how at a 10% interest rate to fund his retirement goal?

Assume that Stephanie accumulates savings of $1 million by the time she retires. If she invests this

savings at 8%, how much money will she be able to withdraw at the end of each year for 20 years?
