OpenAI can't do percentages?

A user on reddit.com's dev_community questioned OpenAI's ability to handle basic percentages, asking if anyone trusts them to get such fundamentals right. The user provided an example scenario: a 10% discount for buying 10 items and a 30% discount for buying 100 items. However, the user noted that this was "not according to the price," implying a discrepancy or error in OpenAI's calculation or understanding of the discount structure.
