The store bought a batch of shirts at a price of 80 yuan, and set the price according to the profit margin of 25%. Because the price was too high, 150 shirts were not sold after a few days, so the store sold the shirts at a 10% discount. After a few days, the manager counted and found that a total of 180 shirts were sold, so he sold the last few shirts according to the purchase price. In the end, the store made a total profit of 2,300 yuan. How many shirts did the store buy in total?
