How did you get to that? I thought I had it wrong I just divided £30 by 15p.
yes the first part is 30/ 15p but that gives you KWh, not hours... go get the number of hours, you had to divide KWh by KW, 200/8 = 25 hours you'll get one mark though, sooo many people put 200, cos they forgot to divide by 8, luckily for me, this same question came up on a past paper, but obvs with different numbers, so i knew how to do it
Oh yhh LOOOOOL wtf is wrong with me I kept it as 60 months at the time I thought 24 months was a year....hmmmm.... (im an idiot) hopefully i wont lose a mark for not simplifying
