The Spring Festival is coming, my mother has prepared a lot of new year's gifts
Mother bought Xiaoming a set of clothes and a pair of shoes, sharing 360 yuan. It is known that the price of a set of clothes is 2.6 times that of a pair of sports shoes. How much does it cost to buy a set of clothes and a pair of sports shoes?

Question 2: 5 × 35 = 175
300－175＝125
