    Hi,
    I was doing this question and I have one of the values for part (b) but I'm unable to get the second value.

    I got a<3.75 (15/4) but I am not too sure as how I should get the full inequality which is:

    3<a<3.75

    No working out required. You have just missed that in the question it says a > 3, which will obviously complete your inequality. Not to worry, simple mistake.

    You have the inequality the wrong way round, remember when you divide by a negative number, you have to change the inequality sign.

    That inequality doesn't make sense, and you got the answer wrong, it should be a<3.75.
