Answer:
Since Jean makes a higher flat rate than Tyshawna, they won't make the same amount in a day. Jean makes a flat rate of 75 dollars a day, while Tyshawna makes a flat rate of 65 dollars a day. Tyshawna is only a few flat rates behind. Although it would seem like they could make the same amount, they wouldn't be able to. If they both had the same flat rate, they would be making the same amount almost everyday.
I hope I helped :)
