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.

B. 500

good luck
