A full tin of paint has a mass of 22 kg. When the same tin is 3/4 filled with paint, it has a mass of 17 kg. What is the mass of the empty tin

2 kg

Step-by-step explanation:

3/4(22-x)=17-x

66/4-3/4x=34/2-x

33/2-3/4x=34/2-x

1/4x=1/2

x=2

that's 2kg because 22*.75 is 17 the difference is -5 each time. 17- another 5 is 12 or 2/4 the original amount. you keep going and at the end you are left with 2kg
