Explanation / Answer

Percentage change in per capita at the end of 10 years:

Country A: 1.22%

Country B: 1.48

Percentage change in Country B in comparison to Country A:

(1.48 – 1.22) / 1.22 = 0.26 / 1.22 = 21.3%.

Percentage change in per capita at the end of 50 years:

Country A: 2.69%

Country B: 7.11%

Percentage change in per capita in Country B in comparison to Country A

(7.11 – 2.69) / 2.69 = 4.42 / 2.69 = 164.3%
