An air-conditioning unit costs $470. In December, there was a discount for Christmas of 16%. After the Christmas discount, the company offered an additional discount for a limited time on energy-efficient models at 7%. 6 months later, the holiday season was over and the company raised the price of the air-conditioning unit by 12%. In addition, due to an increase in production costs, there was an additional 8% increase in the price. In November, the company offers a seasonal promotion with a 10% discount on the final price. How much will an air-conditioning unit cost in November considering all these changes?
