The number of bacteria present in a laboratory
sample after t days can be represented by 500(2).
What is the initial number of bacteria present
this sample?
A. 250
B. 500
C.
1,000
D. 2,000

The answer is B.500

Step-by-step explanation:

The original equation containing unknown variables would be 500(t) (with "t" representing the number of days)

So if you fill the variable in with a 2, that means it's been 2 days with the increase of 500 bacteria each day.

That means the initial number of bacteria must be 500.

If it's been 2 days and you want to determine the bacteria number, then multiply 500 by 2 and you get yourself 1000 bacteria.

mean, 40.6
