Kindergarten 7313

The children in the kindergarten drank 20% of the prepared tea in the morning. They drank another 10% of the left tea afternoon. After the whole day, there were still 9 liters of tea left. How many liters of tea was prepared in the kindergarten in the morning?

Correct answer:

x =  12.5

Step-by-step explanation:


0.20 x + 0.10(x-0.20x) + 9 = x

0.20·x + 0.10·(x-0.20·x) + 9 = x

0.72x = 9


x = 9/0.72 = 12.5

x = 25/2 = 12.5
