Answer:

B. -20

Step-by-step explanation:

8/d = -12/30

We can use cross products to solve

8 * 30 = d* -12

240 = -12 d

Divide each side by -12

240/-12 = -12d/-12

-20 = d

You notice there are significantly more spores at 4th hour than the first, therefore, this is an increasing trend. 

Hope I helped :)
