Removing 3205

The baker filled the bakery flour hopper to 3/4 volume. After removing 875 kg of flour, he filled it with only 2/5 of the volume. How many tons of flour is in the full hopper?

Correct answer:

x =  2.5 t

Step-by-step explanation:

3/4x - 0.875 = 2/5 x

3/4·x - 0.875 = 2/5·x

7x = 17.5

x = 17.5/7 = 2.5

x = 5/2 = 2.5
