Answer:
2) Austria-Hungary
3) Germany
Step-by-step explanation:
The percentage increase in per capita expenditures on armaments from 1910 to 1914 is given by:
Percentage increase = [(per capita in 1914 - per capita in 1910) / per capita in 1910] * 100%
a) France
Percentage increase = [(7.07 - 6.47) / 6.47] * 100% = 9.27%
b) Austria Hungary
Percentage increase = [(3.10 - 1.68) / 1.68] * 100% = 84.5%
c) Germany
Percentage increase = [(8.19 - 4.06) / 4.06] * 100% = 101.7%
d) Britain
Percentage increase = [(8.23 - 7.29) / 7.29] * 100% = 12.9%
