Am I the only one who thinks that in the western world, beside Japanese also Aussies are good in mathematics. (stereotyping)

[Trent]

Nope, i suck at maths lol

Yes, I think all of America stereo types Asians to be very very smart.

Yes, I think all of America stereo types Asians to be very very smart.

That's usually because Asian kids are disciplined by their parents, usually forced to read or go to after-school educational activities and stuff... Luckily my parents don't force me to do that

Help me guys, this problem is awesome :S it's for 10 points to deliver 1 week :S

Three salesmen had arrived at the same time at the only motel in town with a vacancy. The motel had only one room vacant but the men, all road weary from driving long distances, decided to share the room and split the cost.

"How much for the room?" they asked.

"Thirty dollars" replied the clerk. (I know what you are thinking - $30 for a room, give me a break - think of it as a small room in a small town. <g>)

Each salesman handed the clerk $10 (3 X $10 = $30) and they went to the room.

After the men left the lobby, the clerk rechecked the room rate and discovered it was only $25 and not the $30 she had charged the men.

Not knowing how to divide the $5 overcharge, she decided to give each man $1 and pocket the remaining $2 ( 3 x $1 = $3 + $2 = $5).

Each guest had now paid $9 ( $10 - $1 =$9) for the room making the total paid $27 (3 x $9 = $27). The clerk had pocketed $2 bringing the total to $29 ($27 +$2 = $29) leaving $1 unaccounted for ($30 - $29 = $1).

Those are the circumstances. The problem lies in the unaccounted for $1. Where did it go?

There is one, and only one, answer to this math problem. To help you solve it, here are some hints.

1. The $1 was not charged as any sort of tax

2. The clerk pocketed $2 and not $3

3. The men received $1 each and not $1.33

4. The $1 was not spent in the vending machine or at the bar

5. She was the only clerk on duty when the men arrived

6. She did not lose the $1

7. She did not give the $1 to a friend or anyone else

8. This problem is not about how much each man paid

9. The dollar was not put back into the register

Meh, nice one. I think this is how it works :p

They ultimately had to pay 25 bux, not 24(the problem says "9x3". Thats 27. But I went a step further and 8x3 is only 24 and they paid 25) . 25/3 = 8.33 per person. Plus, each person paid one extra dollar, so thats 9.33 per person.

9.33 x 3 persons = 28. Plus the 2 dllars that the clerk pocketed makes it 30.

I think thats it.   

 :ps: Yes the question says "its not about how much each man paid" but my lil brain comes up with only this answer

Well.. Israel counts in as a westren country, and 85% of the kids in school suck at maths... and 55% from the kids that suck at math, are actually failing in math..
Luckly I'm good at maths

Australians in no way stand out for their competence in mathematics and our education system is of a lower standard then a lot of other countries (especially Asian countries). This is especially true with the "original Australians" ie. Aboriginals and massive bogans (if you don't know what a bogan is, think of the Austrlian version of an American hillbilly), but due to so many more immigrants now, things are more spread out. I'm not being racist, I'm just telling it as it is and any Australian would know this. However, Australian Asians stand out within Australia because as Cane mentioned, typical Asian parents are very strict and quite involved in the education of their children.

hmm Australians like me arent smart ive failed math ever since first grade :/

Use the 4 step math plan, I need someone to help me figure out this problem... http://teacher.scholastic.com/lessonrepro/lessonplans/steppro.htm

A banquet hall contains only chairs and round tables, and has 10 chairs at every table. Each table has 8 legs and each chair has 4 legs. The total number of legs on all of the chairs and tables is 960. What is the maximum number of people that can be seated (one per chair) at a banquest hall?

This question its self is easy, its 200 chairs, 20 tables, and 200 people. But how the hell am I supposed to write out this "plan" of solving it.... I just dont get the 4 step plan and hopefully someone else  does.

My answer :

Step 1

Let the number of tables be 'x' and the number of chairs be 'y'
8x + 4y = 960 (given in the question)

Step 2

In one set of tables and chairs we have one table and 10 chairs. (given in the question)
Total number of legs in one set = 8 legs(for the table) + 40 legs(for the 10 chairs) = 48

Step 3

Total number of sets = 960/48 = 20.
Each set has 1 table. Therefore number of tables = 20.

Step 4

Substituting the value obtained in step 3 in the equation in step 1 :

8x20 + 4y = 960
4y = 960-160
4y = 800 or y =200

Wow, just wow  I am defintly using that for the assignment. Its 10 times better then what I wrote up. And looks way more neat in that form. Thank you alot!!

I always had the "I hate school" attitude, but now that Im coming closer and closer to the end of my school life, im starting to realise school is the best time of your life, once its over, you wont see all your friends etc. Everything changes

I hate change
