A few children are traveling. If they buy 2 sun hats and 3 bottles of mineral water, it will cost 52 yuan. If they buy 1 sun hat and two bottles of mineral water, it will cost 28 yuan.
Suppose the mineral water costs X yuan and the sun hat costs 28-2X yuan
2(28-2X)+3X=52
56-4X+3X=52
X=4
28-2*4=20 yuan
Each bottle of mineral water is 4 yuan, and the price of each sun hat is 20 yuan
