GPT-4o claims "This implies she did not pay the full $20. The total cost of the balls and bats she has is less than $20, but she still has items worth up to $20.", then bruteforces an 'answer' of "Balls = 25 Bats = 13".

It also managed to get the prices of the ball/bat wrong, presumably because it's using the more typical riddle:

> Ball = x dollars

> Bat = x + $0.05 (since it’s 5 cents more than the ball)
