The number of bacteria growing in an incubation culture increases with time according to B=9400(5)x, where x is time in days. Find the number of bacteria when x=0 and x=4.
Possible answers:

You can put this solution on YOUR website!
B=94000%2A5%5Ex
When x=0 --> B=94000%2A5%5E0=94000%2A1=94000
When x=4 --> B=94000%2A5%5E4=94000%2A625=5875000

EXTRA:
If I did not have a calculator, I would still know that C) is the right choice, because
When x=4 -->
and 5,875,00 is the only multiple of 5,000 in the lot.
