Answer:
b. 17%
a. Czech Republic and Slovakia.
d. Spain
Explanation:
IN order to calculate the percentage of the increase in his daily salary you have to do a rule of three, the change in money is plus $20 and you just use a rule of three:
\(\frac{x}{100}= \frac{20}{120}\)
Now you just have to clear the x:
\(x=\frac{100*20}{120} \\x=\frac{2000}{120} \\x=16.6667\)
Rounded to the nearest whole number that would be 17%.
In the 1990´s Czechoslovakia split into two different countries the Czech Republic and Slovakia, exactly on January first 1993 both countries dissoluted Czechoslovakia into two different countries mainly due to differences in the GDP of both entities and different needs and goals.
The only country in the list that was not German Occupied by 1943 was Spain, this was because Franco, spanish dictator allowed spanish citizens to volunteer to fight for Germany as long as they fought in the west front agains the soviets.
