Molodets [167]

Answer:

28.25 million

Step-by-step explanation:

Population of the country:

  • in 2001 - x million
  • in 2006 - 30.4 million

Population of the country as percent:

  • in 2001 - 100%
  • in 2006 - 100% + 7.6% = 107.6%

Write a proportion:

\dfrac{x}{30.4}=\dfrac{100}{107.6}

Cross multiply:

107.6\cdot x=30.4\cdot 100

Divide by 107.6:

x=\dfrac{30.4\cdot 100}{107.6}=\dfrac{3,040}{107.6}\approx 28.25
