Figure shows the annual sales for toys, books and stationary of a retail chain store for the year 2006. In general, the sale for each of the item varies with month. We can see that the sale for toy at the highest point in the month of November. This is mainly because of the demand for it due to the Malaysia school holiday season. Another reason is because most of the people bought the toy for the preparation of an event, e.g. Christmas, which comes in December. As we know, the price for these toys would rise in the month of December due to high demand towards it. Next, we can see maximum sale for books and stationary at the month of December, followed by the month of January and February. Most of the reason is due to the beginning of the new school year for the student.

Next, we can see maximum sale for books and stationary at the month of December, followed by the month of January and February. Most of the reason is due to the beginning of the new school year for the student. The figure also shows that the sales for book and stationary begin to rise from the month of July to October. The reason that contributes to this factor is most of the students begin to prepare for their year end semester exam which normally held between the late of October and the early of November. Finally, we can conclude that the sale of the chain retail store changes with month. Besides, the sale for books and stationary is highest at the schooling period, while sales of toys will be highest at holiday or festive season.

Is this ok?
1) Actually, the conclusion I made, I still feel strange about it. I not sure if it is ok for the conclusion.
2) At the figure there is numerical value which represent the sale amount for each of the particulars but I dint use it, is it ok?

3) "In general, the sale for each of the item varies from one month to the next."
The sale in this sentence is a noun am I right? And if it is, is it singular due to sale is uncountable?
4) I presume the 3rd question I say is correct, sale is a noun for the sentence. Then
"In general, the sale for each of the item varies from one month to the next."
Compare with
"In general, the sale for each of the items vary from one month to the next."
Compare with
"In general, the sale forbooks, stationary and toys vary from one month to the next."
Compare with
"In general, the sale forbooks, stationary and toys varies from one month to the next."
Which one is correct which one is wrong and why? or there is a choice between 4 of them?
thanks Kevin for examining my essay

Yes, it's a noun. But it is countable. It is singular because sale is a singular noun.
For example, if I am a bad salesman I might make only one sale, but if I am a good salesman I might make many sales.

So, it is countable, but you used it correctly.

The sales vary.
In general, the sales for each of the items vary from one month to the next."

You could also say the number of sales varies.

The sales vary.
In general, the sales of books, stationary and toys vary from one month to the next."

The number of sales varies.
The sales vary.

You know what? You are great already. Even highly educated people who speak only English do not usually have error-free writing. So, you are already very, very good!

Oh! I just figured out what you mean. Yes, you can use sale as an uncountable noun.
In general, the sale of books, stationary and toys varies from one month to the next."

Here is how I would do it:
In general, the number of sales for books, stationary and toys varies from one month to the next."

sorry for the late reply Kevin, i have some confuse here regarding the last reply.. so you meant that
A)In general, the salesof books, stationary and toys vary from one month to the next."
Sales = Plural
B)In general, the sale of books, stationary and toys varies from one month to the next."
Sale = Uncountable, thus assume to be single
both correct?

Yes, treat it like it is singular. Great question.

B) In general, the sale of books, stationary and toys varies from one month to the next."---This is okay, but a bit confusing. I would do this:

In general, the sales of books, stationary and toys vary from one month to the next."
