How the **** can anyone get those two questions wrong? All you need to do is read them for a minute and do a simple algebraic operation (for the bat and ball).

I still don't get it. The five cent answer is only true IF the ball costs 5 cents, but if the ball costs ten cents then the dollar and five cent answer is no longer true. If the ball costs ten cents then the bat would cost one dollar. Same logic, is it not? This seems so obvious to me, but maybe I'm missing something.

x + (1 + x) = $1.10

2x + 1 = $1.10

2x = .10

x = .05

There's only one answer here..

Wow, got both those questions wrong. That honestly sounds a lot like me. In calc I'm more likely to get the multiple choice questions wrong vs. the open ended because I don't check them and I assume if I got an answer that was listed it has to be right! Man that's an eye opener.

Also linked myself to a site about the "need for cognition". Also interesting. Learning aboot meself.

Got both of those right, wasn't too hard

BS. that's just as dumb as th people saying it can't be 10 because it would only be 90 cents more. The ball is 10 cents, 10 cents plus 1.00 is 1.10. You can do it both ways.captainqwark20

If the ball costs ten cents then the bat costs a dollar more, which is a dollar and ten cents. The total cost is a dollar and ten cents plus ten cents, which does not add up to a total of a dollar and ten cents.

Bll is 10 cents, because 10 cents plus 1.00 is 1.10 where are you getting the extra 10 cents? captainqwark20

You are buying a bat and a ball. In order to get the cost of a bat and a ball, you have to add the cost of the bat to the cost of the ball.

[QUOTE="captainqwark20"][QUOTE="MetroidPrimePwn"] The question has two conditions: The bat has to cost a dollar more AND the total has to be a dollar and ten cents.

If the ball costs ten cents then the bat costs a dollar more, which is a dollar and ten cents. The total cost is a dollar and ten cents plus ten cents, which does not add up to a total of a dollar and ten cents.

The question: A bat and ball cost a dollar and ten cents. The bat costs a dollar more than the ball. How much does the ball cost?

If the ball costs ten cents and the bat costs a dollar, does the bat cost a dollar more than the ball?

ahh ok i get it...

110 cents = 100 cents + 10 cents.

the bat (100 cents) is NOT1$ more than the ball (10 cents).

Its only 90 cents more.

I like what you're trying to do here, but the unfortunate problem is that since this isn't a religion, racism, or my little pony thread, most people aren't going to reply very many times, where as getting someone to realize an error in their own thinking (or in your case, getting someone else to go through the process of getting someone else to realize an error in their thinking) is something that requires a lot of steps and a lot of back and forth.

I like what you did as an extension of the article, though. It really adds something to this discussion, and might get a few people to think more about how to go about improving their ability to explain things to others rather than just criticizing what they see others do wrong.

[QUOTE="spideyredx"]I think I know how this question is "deceiving" you. Ill try to help: you are reading the question like this: The bat + ball = $1.10. IF the bat = 1.00 , how much is the ball? The ball must obviously be .10 and the bat is 1.00. together they equal $1.10 This is not what the question is asking. The actual question: The bat + ball = $1.10. If the bat = 1.00 MORE than the ball, how much is the ball? The bat is NOT 1.00. The bat IS 1.00 MORE than the ball. the bat and ball have to both equal 1.10. If the ball is 10cents and the bat is 1.00 MORE than 10 cents, you would have $1.20. $1.20 is the red flag. The final answer has to be 1.10 instead. The only way for this to happen is if the ball is 5cents. Now, with the ball being 5cents, the bat can be 1.00 MORE than that, which is: 1.05. Now, bat (1.05) + ball (.05) = $1.10 captainqwark20

x + (1 + x) = $1.10

2x + 1 = $1.10

2x = .10

x = .05UCF_Knight

It doesn't get more cut and dry than that.

Finally, I can use a fancy description to label myself "smart".

Yay.

[QUOTE="-Sun_Tzu-"]

[QUOTE="captainqwark20"] Again the what a person would think is: a dollar more than the ball? Yes, 1.00 is 1.00 more than 10 cents. Until you can actually explain it without using mind short cuts the answer is still 10 centscaptainqwark20

The whole point of the article is that the mind likes to take shortcuts. Sure, its fairly easy to calculate the cost of the ball using algebra, but a lot of minds get fooled by the quick solution. It's like those trick questions when they ask what color is this word. The word is blue but its written in red letters. So people say blue.
