At the beginning of an experiment, a scientist has 328 grams of radioactive goo. After 90 minutes, her sample has decayed to 41 grams. What is the half-life of the goo in minutes? Round to whole number. Find a formula for G(t), the amount of goo remaining at time t. G(t)= How many grams of goo will remain after 59 minutes? Round to two decimal places.
