Step-by-step explanation:
<u>Population of Grizzlys</u>
1970 >>> 270
2005 >>> 115% INCREASE
We need to find 115% of 270 and increase 270 by that amount. Firstly, converting percentage to decimal (division by 100):
115/100 = 1.15
So, that would be now:
1.15 * 270 = 310.5
Increasing, we get:
270 + 310.5 = 580.5
We round to 581
In 2005, the population was about 581
