During the Dragon Boat Festival, a shop bought a batch of zongzi for 5000 yuan. During the festival, each box was sold at a price of 30% higher than the purchase price, and 80 boxes were sold. After the festival, each box was sold at a price of 5 yuan lower than the purchase price, and the remaining zongzi were sold out. The whole business process made a profit of 1100 yuan. For the purchase price of each box of zongzi, please use the number of boxes to set the fractional equation, not the profit
