A loopful of bacteria containing 1000 bacterial cells is inoculated into a nutrient broth and incubated.The culture was in lag phase for 10 minutes and then went into exponential log phase growth for 5 hours.The generation time for the bacterium is 15 minutes.Which equation set up is the correct one to determine how many cells at the end of the 5 hours of log phase growth.

The generation time is 15 minutes, so in 5 hours (300 minutes), there are 20 generations (300/15 = 20). The number of cells doubles every generation, so the equation is 1000 X 2^20.
