Question

In a field of wildflowers, the number of flowers is decaying exponentially. One year there are 1,200 flowers, and the next year there are 900 flowers.

The percent of decrease is _____ and the decay factor is _____.
33% .75
20% .67
30% 1.25
25% .70

Answer 1

What the other person said

Explanation:

Answer 2

25% .70

Explanation:

If we subtract 900 from 1,200, we get 300. If we take 300 and multiply it by 4, we get 1,200. meaning that 300 is going to be 25% so since 300 is taken away, the decrease is 25%. Im not so sure about the decay factor but since 25% .70 is our only answer with a 25% decrease, our answer is going to be D.
