"A student builds a bot that solves math problems. It gains 5% more users each hour, starting with 500 at midnight. However, each teacher user reduces growth by 2% per teacher. At 8 AM, 20 teachers join. Write a differential equation modeling the bot's user base. Solve for t when the system stabilizes." It was from the teacher certification exam —a
