    g (f (x)) = 3.15x

    Step-by-step explanation:

    To find the number of Japanese yen equivalent to x russian rubles, we need to put one function into another.

    If we take f (x) and put in into g (x), we will get Japanese yen in terms of rubles. Thus,

    g (f (x)) = 90 (0.035x)

    g (f (x)) = 3.15x

    THis is the composite function which represents the number of Japanese yen equivalent to x Russian Rubles.
