ehidna [41]

Answer:

Year 2034

Step-by-step explanation:

In 2000, 64% had one or more pets

<em>Since decreasing at 1% per year, we can say:</em>

<em>In 2001, 63%</em>

<em>In 2002, 62%</em>

<em>In 2003, 61%</em>

<em>In 2004, 60%</em>

<em>And so on</em>

<em />

To go to 30% from 60% in 2004, we would need to decrease 60 - 30 = 30%, and that will occur after 30 more years. So that would be the year

2004 + 30 = 2034

So, year 2034
