Building a better biped: The easy answers

[Requia ☣]

Actually, the better your brain naturally works at math, the more likely you are to get it wrong.  What happens is there are easy ways and hard ways to process the answer, when an easy answer pops up, the other processes never trigger.  Getting it right relies on checking your answer.

Do it in reverse, if the ball is 10 cents, and the bat is $1 more than the ball, the bat is $1.10, so the bat and ball total $1.20.

I think the main problem is that english sucks, when it comes to math.  Bat is one dollar more than ball, both together equal 1.10.

X+(1+X)=1.10

so,

X+X=.10

so,

X=.5

There you go with that fucking 'X' thing! That's exactly my problem with maths

It's a metaphor, silly.

Bat is one dollar more than ball.  That means [the cost of ball] added to [one dollar plus the cost of the ball], is 1.10.

so,

Ball + (1+Ball)=1.10

so,

Ball + Ball=.10

so,

Ball =.5

STFU!!!

For the record, when I read the original post, my first instinct was to say the ball cost ten cents.


I knew that I could do the maths, I was just lazy; and so, I got it wrong because the answer was not "intuitive" to me.

Prolly cos my maths is the suck or something I got it right almost straight away (although I did want to try 10c first) I saw the words "more than" so I knew I had to add the bat and ball price together then add the ball again and compare to the total. Straight away I got 1.20 and figured it must be a different price.

A Five cent ball and a dollar and five cent bat are gonna be pretty shitty toys... that's like Dollar General quality there.

If you buy your kid a bat and ball at those prices, you are a terrible parent. They probably came from China and are full of lead, asbestos or some other horrible thing... not to mention the Baseball Sweat Shops that they were manufactured in!!!

The question is from the 60s, inflation has made it a bit obsolete.

Repackaged for the modern age:

A bat and ball set are on ebay with a - buy it now - price of $29 if the Bat is $15 more than the ball and the ball is $1.50 then WTF????

ETA: Okay maybe someone with a better grasp of math should attempt this

Ten Bucks! ... no wait ...
