To calculate the formula, to ensure correct! Comprehensive process! Thank you~
Suppose the price of mineral water is x yuan, then the price of eight treasure porridge is 4x yuan, then the price of milk is 12 × 4x yuan
5x+8×4x=68
x=68/17
The price of mineral water is 68 / 17
The price of eight treasure porridge is 4x = 4 × 68 / 17 = 16
The price of milk is 12 × 4x = 192
