In America we would ask "How much does he make?" More often than "How much does he earn?"
Why couldn't this mean "How much did he win?"
How much do they make = combien gagnent-ils
How much does he make = combienn gagne-t-il
Both have the same pronunciation.
I wrote the former, and got it wrong. Not sure how one is supposed to know, aside from context when talking to a real person in a real conversation.
I would like to know also if "How much did he win" is also correct.
Quelle est la différence avec "combien gagnent-ils"?
