The correct answer is option D.
F(G(x)) denotes the composition of the two functions F(x) and G(x). The composition of two functions result in x, if the two functions are inverses of each other. So in this case F(x) and G(x) will be the inverse of each other. So option D is the correct answer.

Step-by-step explanation:
mean : added up the values and divide the result by the number of the values 
Mr Jones = (5 + 6.25 + 5.75 + 6.50 + 8)/5 = $6.30 
Mrs Jones = (5.50 + 7 + 6.25 + 5.75 + 7.75)/5 = $6.45
