At the beginning of an experiment, a scientist has 400 grams of radioactive goo. After 150 minutes, her sample has decayed to 25 grams. What is the half-life of the goo in minutes? Find a formula for G(t), the amount of goo remaining at time t. G(t) = How many grams of goo will remain after 14 minutes?
