Well, she's advertised as a pretty woman, not a smart one.
And now, with a little less jest: It's a stable income over a week, with a guy she evidently likes to at least look at. No need for advertising in that time. Meals are paid, as is time off. Also, the 21$ assume that she is paid 24 hours a day (3000$ ÷ 24 ÷ 6 = 20,83333...$) so she gets paid for sleeping, eating, essentially her own time. She also gets the opportunity to scout new, well off clients.
3k pays your rent in San Fran with cash left over in that time period...ur damn right she's hanging out with a rich dude and getting spoiled for a week and her rent paid.
Mf out here acting like they're breaking down door dash hourly.
It's also 8 hrs/day she doesn't have random sweaty fat guys dumping loads in her. Anyone who doesn't take that deal is either Ayn Rand level deranged or has beaten life and found their true passion
We need to consider how many hours in a day she would normally get paid the $100/hour rate. Or said differently, how many hours does normally work in a 6 day period
She would need to work 30 billed hours in 6 days to break even on her normal rate
