Answer:
She has 43 marbles.
Explanation:
Okay so, she had 23 yellow marbles, Tim took 22, which means she had 1 left.
Afterward, she gave 10 marbles to jack. Doesn't specify which color, which means that it's just random marbles. Let's take 10 reds to make this easier. So, 43 - 10 = 33.
So, we had 1 yellow marble from before and 33 red marbles. 33 + 1 = 34.
