Answer:

The bear population gained 70%.

Step-by-step explanation:

  • As there are 10 black bears in an area.
  • By rule of three, we consider that 10 bears represent 100% percentage.

Let is us consider 'p' denotes the current percentage of bears.

so

  • 10 → 100%
  • 17 → p

so

p=\frac{17\times 100}{10}

p=\frac{1700}{10}

p=170

Subtract 100 from the 170 to determine the percentage of increase

170-100=70

Therefore, the bear population gained 70%.
