Tang:

Simon has some money.
He spends $10 on 3 exercise books and 7 pencils.
He will be short of $0.40 if he were to buy another exercise book.
He will have $0.60 left if he were to buy one more pencil.
(a) How much does each exercise book cost?
(b) How much money does Simon have?

The original question is perfectly all right. The information will give us 'An exercise book costs $1 more than a pen'.

Hi Tang

Can help to explain please.

\"He spends $10 on 3 exercise books and 7 pencils\" would means the total cost of 3 books and 7 pencils is $10.

\"He will have $0.60 left if he were to buy one more pencil.\" would means the total cost of 3 books and 8 pencils is $9.40.

How come more pencils will cost less?

3 B + 7 P = 10

1 B - 1 P = 1

It was not stated that the amount of money he has is $10.

Anyway, this will be my last post in any forum. As I have been offensive for 3 incidences, I am now banned by my parents with immediate effect. Good luck to all. Bye.

Hey Tang

Please don't leave this forum. Your postings were never offensive. Instead they were the more informative and useful ones that I enjoy reading and pondering over. I am sure all others here will agree with me.

Just like this clarification you have given. It is so clear and enlightening. Otherwise I will still be spending hours thinking over it.

Hope to read your postings again.

Yeah, Tang...

You're posts were, on the contrary, giving us insight into new ways around stuff that we hadn't seen before! You're posts were just posts that were looking at things from a different angle, not offensive ones! If you leave this forum, everyone would be like this: :!:

Hope that you will soon be back, solving the mind-baffling problems that elude us everyday!

Simon has some money.

(a) How much does each exercise book cost?
(b) How much money does Simon have?

Dear Suiyuan,

Here's my solution. Just like what Tang mentioned, an exercise book costs $1 more than a pencil. You can ask your child to try drawing out the model, sentence by sentence, to visualise it.

Hi Tang,

Please continue to share your solutions as we all welcome other methods of solving a problem. We can all learn something from one another.

(a) How much does each exercise book cost?
(b) How much money does Simon have?

the exercise book cost $1 more than the pencil.

so each pencil costs $0.70
and each exercise book costs $1.70 (a)

$10 + $1.70 - $0.40 = $11.30 (b)
