# C1 Question, Help? Watch

1. 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

2. 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.
3. You have the inequality the wrong way round, remember when you divide by a negative number, you have to change the inequality sign.

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

that's what I meant, well it should be 3<a<3.75
