This year = 18kg
18 x .3= 5.4
The percentage change would be 5.4%. If it needs to be rounded by the nearest tenth, then it would be 5%.
I’m pretty confident this is the answer but I’m not 100% sure. I hope this helps!

Multiply both sides of the equation by 3.

Subtract 6x on both sides.

Combine 2x and −6x to get −4x.

Add 20 to both sides. Any value plus zero results in its same value.

Divide both sides by −4.

Divide 20 by −4 to get −5.
