Question

The grizzly bear population in Yellowstone National Park in 1970 was about 270. Over the next 35 years, it increased by about 115%. What was the population in 2005?

Answer 1

581

Explanation:

270x%115=310.5

We have to round 310.5 to the nearest So 310.5 will be 311

So if it increased by 115% we have to add the 115% to 270

270+311= 581

By the 2005 the population will be 581

Answer 2

Answer: 311 bears

Explanation:

Population increased by 115% in the 35 years from 1970 to 2005.

Population in 2005 is:

= 270 * 115/100

= 310.5

= 311 bears
