In this question , it is given that the number of a country's unemployed workers decreased from 3.4 million to 5.5 million last year.
First we have to find the percentage of unemployers, that is
[tex] \frac{3.4}{76}*100 , \frac{5.5}{76}*100
\\
= 4.47 % , 7.24% [/tex]
So the percentage of unemployers change at a rate of
[tex] = 7.24 -4.47= 2.77% [/tex]
