apsig...:

Thanks for answering BUT

Why did you answer it in a place where the question is not.  It is super confusing and I am not the only one who has said so.

 

KINGCASH:

You have been given an answer but you did not comment on it.  

Did you try to work through it.

You keep reposting, why would you do that without even commenting on the answer that a kind person has given you.

Do you think that is a nice way to treat a person who has tried to help you?

Here is the answer that apsig... provided you with.

Please look at it properly and then comment on it ..... maybe say thankyou.

If you still do not understand or want more help, ask for it politely.

 

 

 

    20¢       50¢                         
  Box A : Box B                Diff Box B -- Box A

     2      :  1                    0.50--0.40 = $1.60


0.20 * 2 : 0.50                     0.104 = 1.60

0.40¢                                        u = 1.60
                                                       ------

16, 0.40¢ Coins Box A                    0.10

32, 0.20¢ Coins Box A       u = 16

 

The answer choice is C

I just realized that maybe apsig... answered on the other thread because this one was locked.

If that is the case then I apologise for being a little bit snarky about it.

 

 

If anyone wants to continue a locked thread they just have to send a personal message to a moderator, asking for it to be unlocked.

Or I suppose if they are a guest, or they just want to,  they could make a new question post just requesting that a given thread be unlocked.

Obviously they would have to include the address. I guess it should be titled    "Attn Moderator : please unlock this post"
