The word
billion can be omitted from the prompt, as follows:
175 French francs is equivalent to 35 United States dollars.
Which of the following expressions represents the number of United States dollars equivalent to f francs?
Let f = 350.
Since 175 francs is equivalent to 35 dollars, twice the number of francs -- 350 -- is equivalent to twice the number of dollars (70).
Thus, the correct answer must yield 70 when f=350.
Only D works:
f/5 = 350/5 = 70
The correct answer is
D.
