ok i gave it a go but i know its not right.

i have 47.25kilo of bait and it costs £54.75. how much would each kilo of bait cost?

here how i know what i got ended up with is wrong. got this from the bait website:

33.75kg of bait and it costs £47.82 so each kilo costs £4.85. i tried working this out but i ended up with a differnt answer.

its the first one i want working out please :] also if you do work it out could you tell me how?
