Answer

Answer:

The number of weeds is decreasing by a multiplicative rate.

Explanation:

Step1: Analyze the data trend

As days after treatment increase from 2 to 10, number of weeds decreases from 100 to 1.

Step2: Check multiplicative or additive

If it were additive decrease, the difference between consecutive weed - counts would be constant. But (100 - 26=74), (26 - 6 = 20), not constant. If it were multiplicative decrease, we can check ratios. (\frac{26}{100}=0.26), (\frac{6}{26}\approx0.23), (\frac{2}{6}\approx0.33), (\frac{1}{2} = 0.5). The ratios are not exactly the same due to possible data variability, but the general trend shows a multiplicative decrease as the number of weeds is shrinking by a factor each time. So the number of weeds is decreasing by a multiplicative rate.
