Hmm, thought I'd already put my answer to this. Anyway... Let Kim have K pounds, and Amul have A pounds. We know the following two things: A + K = 10.70 (from the total amount) K + 3.70 = A (Since Amul has £3.70 more than Kim). Put the second equation in the first one: K + 3.70 + K = 10.70 Therefore: 2K + 3.70 = 10.70 Subtract 3.70 from both sides: 2K + 3.70 - 3.70 = 2K 10.70 - 3.70 = 7.00 So we are left with: 2K = 7.00 Or, dividing both sides by two: K = 7.00 / 2 = 3.50 So Kim has £3.50. Amul, meanwhile, has 3.50 + 3.70 = £7.20. We can check that this works, and it does fit the total, so is the solution. Hope this helps and is clear.

For such a short problem charging £20 would be rather harsh. Instead I would charge £20 for a whole hour or so of help.

For information: all answers in the homework Question & Answer board are free. It gives students a bit of help, but if they want full one to one online tutoring from a tutor like Jim360, they need to contact the tutor and arrange a session. Hope this helps.

If you are not so keen on algebra (putting the problem into letters and symbols) then think of it this way:

Subtract £3.70 from £10.70 leaving £7.00. Then share that £7.00 equally between the two people giving £3.50 each and add the £3.70 to Amul's so that he has £7.20 while Kim only has £3.50. That can be checked and gives the correct total and the correct difference.
