A shopping mall offers discounts to customers based on the amount spent:
(1) No discount for purchases up to 100 yuan;
(2) For purchases over 100 yuan but not exceeding 300 yuan, a 10% discount is applied;
(3) For purchases exceeding 300 yuan, the portion up to 300 yuan is discounted by 10%, and the portion exceeding 300 yuan is discounted by 20%. Mr. Wang received a 10% discount on his first shopping trip and a 20% discount on his second shopping trip. The mall informed him that if he had made the purchases in one go, he would have saved an additional 19 yuan; without any discounts, he would have spent an additional 67 yuan. How much did Mr. Wang actually pay for his first and second shopping trips, respectively?
