N=8. All you have to do is count the amount of numbers after the 2 in 200,000,000. There are 8 numbers after the number 2 which makes n=8.

34.7% of city employees ride the bus to work. Last year, 5.2% of city employees rode the bus to work. What is the relative chang
DaniilM [7]

Answer:

5.67\%

Step-by-step explanation:

The relative change is defined by the following equation:

Relative\hspace{3}change=\frac{x-x_r_e_f_e_r_e_n_c_e}{x_r_e_f_e_r_e_n_c_e}   (1)

Where:

x=Value\hspace{3}of\hspace{3}indicator\hspace{3}in\hspace{3}period\hspace{3}2

x_r_e_f_e_r_e_n_c_e=Value\hspace{3}of\hspace{3}indicator\hspace{3}in\hspace{3}period\hspace{3}1

With this in mind, let's replace the values in the equation (1):

Relative\hspace{3}change=\frac{34.7-5.2}{5.2}=\frac{29.5}{5.2}=5.673076923\approx5.67\%
