The grizzly bear population in yellowstone national park in 1970 was about 270.Over the next 35 years,it increased by about 115%

yawa3891 [41]

Answer:

581

Step-by-step explanation:

Population of Grizzlys

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
