1. At the beginning of an experiment, a scientist has 540 grams of radioactive Guyradium (Gy). After 100 minutes, the sample has decayed to 300 grams. Assuming exponential decay, find a formula for G(t), the amount of Guyradium remaining at time t. How many grams of Guyradium will remain after 150 a. b. minutes? Don't forget to show your work. Round your answers to four decimal places.
