[q] Managers who go on to earn engineering degrees can make up to $100,000 a year.
What does ‘make’ mean? I guess it might be either [a] or [b] below from Merriam-Webster’s Learner’s.
[a] 14 a [linking verb] — used to indicate a total
[b] 17 [+ obj] : to earn or gain (money, a profit, etc.)
But I’m not sure, for [q] has prepositional complement which I don't find in dictionaries. Which mean do I have to take? Can the prepositional phrase be used with the one you select?
