20) The half-life of Vancestronium is 565 days. If there is 94 g present now, how much will there be in 3 years? (assume no leap-years).
21) (2 Parts) If you invest $3000 today, in an account that pays 6 1/4%, how much will you have in 10 years? How long will it take to grow to $15,000?
22) (2 Parts) A rare mathonium isotope decays at the rare of 3.5% (3 1/2) per day. If there are 86 grams now, how much will there be in 12 days? How long will it take to decay to 1 gram?
