Here's the question..

If the price of an apple was raised 50% and then decreased 50%, making it cost $0.75, how much was the original price?

Choose an answer from the poll above. Let's see who is smart, and who just picks what everyone else chooses..

$1.

1 person so far is really dumb.

 

[DanNicol]

$1 is my guess

So far the majority of the users on the forum now are looking at this thread and the boob one.. Funny how intimidating a simple problem like this could be..

this problem seems really simple to me. and whenever the problem seems this simple to me, I am usually wrong.

 

[Uzzz]

75 until stupid math kicked in... 1 dollar

You're the 75 cents one aren't you?

 

[DruSam]

Trick question you idiots! The answer is zero!

I plead the 5th.

The price of an apple (x) is raised 50% shown as:

x + .5x


Then decreased 50%, so half of the previous formula:

.5(x + .5x)


All that equals $0.75

.5(x + .5x) = .75
.5x + .25x = .75
.75x = .75
x = 1

Yea, I used Google too.

It's $1 and yes I read it and clicked .75 in 5 seconds :eek7:

After thinking about it for 1 minute it's very simple.

.75 is 50% of what? $1.50
$1.00 + 50% (.50) is $1.50

I never thought numbers and letters belonged together, but there is purpose in it! Jerxs-thanks for showing your "work", I'm very bad at math, so it would've hurt my head to figure it out. I'm very visual, so seeing the work helped!

 

[J-Tag]

I don't get it.. why would it be $0.75 to start with?

Originally I thought it was .75 because it was raised 50% and then decreased 50%. So if it starts out at .75, then you raise it 50% and then decrease it by 50% that brings it back down to .75. I honestly didn't know until the jerxs posted the formula. I HATE math. lol

Give us a harder question Jon, and don't do it poll style, just make people post their individual answers w/o work.

Here's one:

The acceleration of a particle is directly proportional to the time t. At t = 0, the velocity of the particle is 400mm/s. Knowing that v = 370mm/s and x = 500mm when t = 1s, determine the velocity (v), the position (x), and the total distance traveled when t = 7s.

Good luck.
