You can joke if you think she's BSing, or try respond in a more logically if you think she's just nervous/ has a legit reason. Either way, definitely don't wait a month.

Joke: "Is it too much to ask you to put your whole schedule aside for one random guy you met on tinder?" (Clearly a joke, nobody will put their entire life aside for a random person on the internet."

Serious: "Hey I get it, work keeps me busy too. But I'm sure we could both try and find time in our schedule for a fun night together."

She's not really investing much. I'd say let it go.
