On average, activated yeast cells divide once every 120 minutes; that is, each individual cell divides into two individual cells over that time span. Given that a certain yeast colony consisted of 310,000 cells two hours ago, approximately how many cells will be populating the colony four hours from now?  Pick
A) 77,500  B) 1,860,000  C) 2,480,000  D) 3,720,000  E) 4,960,000
310,000 × 2 × 2×2 = 310,000 × 8 = 2,480,000
