Russia's population is decreasing by about 700,000 people per year due to high death rates and low birth rates.
If this pattern continues, what will be the total decline over the next 30 years? Use a signed number.
Correct Answer
-21,000,000
Explanation
\[ 30 \times (-700{,}000) = -21{,}000{,}000 \]
Russia's population would decline by 21,000,000 people over 30 years.
