Answer 1

1 US dollar = 0.961 Canadian dollar
d US dollar = 0.961d Canadian dollars.
There is a transaction fee for converting currencies and it is $3 US dollars.
So when converting d US dollars, a transaction fee of $3 will be taken by the bank and the rest converted. Therefore, F(d) = (d-3)*0.961 is the function to convert Us dollars to Canadian dollars. F(d) = 0.961d - 2.883

Answer 2

To convert Canadian dollars c to US dollars:
G(c) = c / 0.961 - 3
G(c) = 1.041c - 3
