The answer should be 3059 francs.
Solution:If each franc has the value of $0.3 then he would been able to pay 924/0.3=3080 francs for it.
If he returned from his trip with 21 francs,
he then must spent 3080-21=3059 francs.
So the answer's 3059.
924美元=92400美分，
1 dollar=100 cents
30 cents=0.3 dollar=1francs
924 dollar=3080 francs
3080-21=3059 francs
He spent 3059 francs
924/0.3-21=3059
so Felix spent 3059 francs in France.
因为我们知道 “ 100美分等于1美元 ” 所以:
924.00×100=92400 cents
又因为由题目得 “ At that time, each franc was worth thirty cents ” 所以法郎的总数为:
92400÷30=3080 francs
我们可以继续由题知道 “ he returned from his trip with ...

我们可以继续由题知道 “ he returned from his trip with 21 francs ” 所以他用去的法郎数为:
3080﹣21=3059 francs
收起
He spent 3059 francs.
