click refresh (F5) of the bacteria growth in a culture dish is killed by ultraviolet radiation.
If bacteria were killed by the radiation,
find how many bacteria (B) were initially in the dish.
Note: round to zero decimal places - no bacteria parts.

The initial bacteria B = bacteria.


Example:

click refresh (F5) of the cities tested in the U.S. added fluorine to their drinking water.
If 42000 cities added fluorine,
find the number of cities (C) tested.
Note: round to zero decimal places - no bacteria parts.
This statement can be written in shorthand form as:

click refresh (F5)

Solving for C gives click refresh (F5) cities

Thus, there were 48000 cities tested.
