<h3>Answer: C) 0.85b</h3>

This is saying 85% of b since 100% - 15% = 85%

You can think of b-0.15b as 1b-0.15b = (1-0.15)b = 0.85b

The population of the town was 25,000 people.Then 3,200 people moved away.What was the percent of increase?
german

Answer:

-12.8%

Step-by-step explanation:

To calculate the percent decrease, we:

  1. Find the difference between the new value and the original
  2. Divide the number by the original
  3. Multiply by 100 and the % symbol.

The population of the town originally had 25,000. 3,200 people moved away. This means that the new population is 21,800.

  1. 21,800-25,000=-3,200
  2. -3,200/25,000=-0.128
  3. -0.128(100)=-12.8%

The towns population decreased by 12.8%.
