well,1.5 kg is 1500g so you can halve 80p and 200g into 40p and 100g. Then you can multiply 40p with 15 which gives you the answer- £6. Sorry if it's lame (which I know it is) but I am only a child.

Well 1kg=1000g and 1.5kg = 1500g so we need to find out how many times 200g goes into 1500g which is 1500/200 =7. 5

We then multiply this by 80p - 7.5x80 = 600p = £6
