>On the first day, Bob lent Rose as much money as she already had. Then she spent $10.
>On the second day, Bob lent Rose as much money as she had now, and she spent $10 again.
>On the third day, Bob once again lent Rose as much money as she currently had. This time she spent $10 and went broke.

How much money did Rose start off with?

I got 8.75

The answer depends on Rose’s Only Fans account.

Interestingly, the equation gets set up correctly, but solved incorrectly! (Should be 70/8, or $8.75)

On the third day, after Bob doubled Rose's money, she spent $10 and then had $0 left. This means that right before she spent the $10, she must have had $10 (since spending it brought her balance to $0).

Now, if Bob doubled her money to get to this $10, she must have had $5 before Bob gave her the money on the third day.

Going back to the second day, after Bob doubled her money and before she spent $10, she had $5. Therefore, before Bob doubled her money on the second day, she must have had $2.50.

Finally, on the first day, she ended up with $2.50 before spending $10 on the second day. This means that before Bob doubled her money on the first day and before she spent $10, she must have had $12.50. Then Bob doubled this to get $25, and after spending $10, she was left with $15, which was then halved to $7.50 by the end of the first day (because Bob had doubled what she started with).

So, working backward, we can determine that Rose originally started with $7.50.
