Question

Suppose the population of a certain city is 3339 thousand. It is expected to decrease to 2694 thousand in 50 years. Find the percent decrease.

Answer 1

-19.3%

Explanation:

The percentage change in a value is computed from ...

percent change = ((new value) -(old value))/(old value) × 100%

= (2694 -3339)/3339 × 100% = -645/3339 × 100% ≈ -19.3%

The decrease in 50 years is about 19.3%.
