<u><em>Commutative:</em></u>
93 + (68 + 7) ⇒ (68 + 7) + 93
<u><em>Associative:</em></u>
93 + (68 + 7) ⇒ (93 + 68) + 7
<u><em>Identity:</em></u>
93 + (68 + 7) + 0 ⇒ 93 + (68 + 7)
We know that
1 Kg is equals to--------------> 1000 g
so
X Kg------------------------> 300 g
X=300/1000------> x=0.30 Kg
if 2 Kg cost--------------> <span>£7.20
0.30 Kg-------------> X
X=0.30*7.20/2------> x=1.08
the answer is
</span>£1.08
