Question

5 There were about 150,000 devils in the 1990s. The population has been reduced by 80% because of DFTD. What's the current population?

Answer 1

Number of devils in 1990 = 150000

Percentage decrease = 80%

Let's find the current population.

To find the current population, we have:

`\begin{gathered} \text{Current population=150000(1-}(80)/(100)) \\ \\ \text{Current population = 150000(1-0.8)} \\ \\ \text{Current popu;lation = }150000(0.2)=30000 \end{gathered}`

Therefore, the current population is 30000

ANSWER:

30,000
