Very Basic Maths Help, Please

[barry1010]

Yes, I know a five year old can do these very simple sums but I don't have one to hand. Can you confirm my calculations are correct?

I used 1.34KW of electricity at 32.11p per KW. I believe that has cost my 43p (+Vat, which I'm not concerned about)

I used 13.87KW of gas at 9.83 per KW. £1.36 + VAT?

[THECORBYLOON]

They are both correct, to the nearest penny.

[roslyn251254]

yes both correct

[barry1010]

Thank you, both, much appreciated

[Peter Pedant]

yeah
put the five yr old back in the attic

The kids , are / were taught to approximate, to get the decimal pt in the right place.

1) is one and thirty two which is thirty two - near enough to 43p

2) is fifteen at ten - which is near to 150 ( pence ) or 1.50 pounds.

simples - no calc needed

[ToraToraTora]

I assume you mean KW hours but yes correct.

[Atheist]

barry; your sums are correct, but the references to KW should be KWh.

A KW is a measure of the rate of flow of the electricity, not the actual electricity used. A KW flowing for a second is next to nothing, but a KW for an hour (KWh) is a lot more.

Why have you got two different prices? Are these just examples?

[Peter Pedant]

Oh Oh
WE were taught arithmetic had to be stripped of units, as it was a maff manipulation: ( and you cdnt multipy 2 apples by two. we all thought you could)

let the cost in pence be 32.11, and let tric-tricity consumed be 1.34.....

Is it true primary kids arent taught multiplication and just count up on finger these days, or was the child in q ( I carnt mooltiploy!) just trying it on ?

[Peter Pedant]

whilst we are worrying about h ( a jot as they say in the bible)
one is gas and one is tric-tricity

and ( hey getting teeeeechnical!) the ratio is 3:1
( quick check - yup looks like it)

[Peter Pedant]

or just read the q

[Atheist]

Thanks PP. Sorry barry.
Yes, I should read the question!

[theshedman]

Does your price include the standing charge which I think is worked out daily or were you just after the cost of the electric.

[Hopkirk]

If you wanted to add the VAT, don't forget it is only 5% on home energy.

[barry1010]

I'm disregarding the standing charges because they are not affected by gas and electric consumption.

I am comparing the cost of doing the same thing by gas and electricity to determine the cheapest method.

[ToraToraTora]

Gas is a lot more expensive per KWH.

[Peter Pedant]

I was charged ( Karen McClintock please note) £25 late payment when I wasnt ( late)
and so non payment was entered on my credit card info with Experian, screwing my credit rating

and karen ( see above) warbled that they cdnt do anything about it, but she assured me it was done in the best parsible taste.

phew - thank god for that

then under the usual threats ( screwing around with your credit rating) I paid one bill twice. ( same amount, difft cheque numbers) and yes they thought it was a double entry and....
Karen like a sullen and unwilling teenager had to correct THEIR mistake.....
good luck

last worse gas supplier

[barry1010]

How can it be, TTT? The Gov UK website states under the energy price guarantee gas is 10.3p per KWh and electricity is 34p per KWh.
The website does say the price varies by region and my gas and electricity are slightly cheaper.

[ToraToraTora]

Apologies barry I got that the wrong way round, yes it's a lot cheaper per KWH but still seems to use a lot more KWHs. eg of my bill 3/4 of it is gas.

[barry1010]

Yes, it is cheaper for me to use electricity than gas to heat my hot water tank. I would have assumed it to be the other way round

[bhg481]

It's obvious that gas is cheaper than electricity because the generating companies use gas turbines. If electricity was cheaper they'd use electric motors to drive the generators.

[Atheist]

bhg; I hope you were joking!
Have you ever tried using an electric motor to turn a dynamo to produce electricity to drive the motor to turn the dynamo......?
