Joe is studying a bacteria population. There are 20 bacteria present at 3:00 p.m. and the population doubles every 3 minutes. Assuming none of the bacteria die, how many bacteria are present at 3:15 p.m. the same day?

every 3 minutes they double, so they double 5 times, or they're population is multiplied by 2^5 or 32. so 20$\cdot$32=$\boxed{640}$
