Punctuation for spoken sentences

[Musicgold]

Hi,

What would be the correct punctuation for the following sentence? This how I said it when I was talking with somebody, but I am not sure how to write it.

I though that a $10 increase in a $1000 account means a 0.1% increase, which is not correct, it should be an 1% increase.

Thanks,

MG.

The grammar of the sentence is incorrect to begin with. You can punctuate this in more than one way:

I thought that a $10 increase in a $1000 account meant a 0.1% increase, which is not correct. It should be a 1% increase.

I thought that a $10 increase in a $1000 account meant a 0.1% increase, which is not correct; it should be a 1% increase.

Jamie,

Thanks. My apologies for the misspelling of 'thought'.

Now regarding the article before '1%', I have seen people using 'an 8% increase' and 'an 11% decrease'. As a result, I though 'an 1%' would be an acceptable construction.
