Answer:
0.4 swiss good(s) per U.S good(s)
Explanation:
firstly we calculate how many dollars we get per Frank so we will say $1/ 5 Swiss Franks =$0.2 which is similar to (5x =1, solve for x =1/5 / 0.2 in simple maths )per Swiss Franc thereafter we calculate the how many Swiss Francs per good compared to dollars per good we can get so therefore 2 Swiss Francs per good/$1 per good is the ratio of comparison , hence we treat f(X) as a function of swiss good(s) per U.S good, therefore f(X)= 2 x , knowing that x= 0.2 f(x)= 2(0.2) which will result in f(x)= 0.4.
