Math Is Fun Forum

Okay see you tomorrow. Bye.

EDIT: By the way I hope your husband makes a speedy recovery.

Good luck with those other two questions, and please do post any answers that you have.
I can mark it earlier if necessary and I do check this website at other times.

You have lopped off the 5 at the end of 29.25 to make it 29.20. This is the only mistake.

The method is correct. There is that one mistake and the answer would/should have been 308.75
I think that is what they call a "silly mistake" as opposed to anything more serious.
Also one point about the presentation of your method. I know what you mean but you have used the equals sign
for two things that are not equal. I don't think that you would lose marks for that at GCSE, but I am not sure and
I wonder what someone like Bob thinks of that. I realise also that you are doing this using plain text, and it may
well be easier when written down to space it out and make things clearer.

EDIT: 29.28 is obviously not right. I think you can see that from the above message.

Okay. I will get to work on that. Give me about ten minutes. Is email or a post to MIF better ?

Okay. I think you should do the final addition again with the basic pay of 262.50
The overtime bit of 40.00 was correct.

Correct. Now let us try another example:

£ 7.50 - hourly rate
35 hours - normal full time hours
4 hours overtime
overtime paid at time and a third

Can you work out the basic pay?  Overtime ?  Total ?

Right the clue is in the "time and a quarter" bit can you work out the overtime rate?

The "7x35" bit was certainly correct and what I was hoping for.
However it is not 49. Quite frankly I grabbed my calculator for that one, but it wouldn't hurt for you to try using a proper
multiplication:

35  x
  7

Hi Mandy. I'm sorry to hear that you were unwell, but glad that you are better. 2:30pm today is okay with me.
By the way just to remind you that you can either post here, or email any attempts to the recent exercises that you want marked.
Yes so we need to go through something on either ratio or the overtime pay thing I would think.

What sort of problem do you wish me to give you ?

Right here is what I would do to work out the gross pay:

£ 6.50 x 39  to get the amount without overtime added.

Then £ 6.50 x 3 x 1.5  to get the overtime pay

Then add the two so  Total Gross Pay = (£6.50 x 39) + (£6.50 x 3 x 1.5)

The use of the 1.5 comes from the "time and a half" bit where we are adding 50%
Now I was trying to explain something like this in the topic on percentages. So you can see here that a basic knowledge of
percentages is essential to understand the calculation above.

Hello Mandy. We could do something on finance/overtime pay. I have not got anything prepared, but we could discuss the topic
and perhaps invent an example of some figures such as a rate of pay, a number of hours worked and the number of hours of
overtime as well as a rate for that overtime. In others words to do an example of that we need some figures such as:

£ 6.50 - hourly rate
39 hours - normal full time hours
3 hours overtime
overtime paid at time and a half

The above is just something that I have thought of off the top of my head you understand (randomly) and the figures will not
necessarily be either realistic or "nice round numbers" then again in real life examples the figures will only rarely be nice and round.

Tricky. If I give you more questions on ratio then that will simply add to things that you don't know how to do.
Bob gave you some exercises as a sort of test of maths that you have recently done. You could do those.
