Teacher: You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues. You are required to assign a label 'formal' if there is an absence of emotion and a presence of questions anywhere within the conversation. If such pattern is not found assign the label 'informal'.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Person1:      Hey man , you wanna buy some weed ?  
 Person2:Some what ?  
 Person 1:Weed ! You know ? Pot , Ganja , Mary Jane some chronic !  
 Person2: Oh , umm , no thanks . 
 Person1:      I also have blow if you prefer to do a few lines . 
 Person2: No , I am ok , really . 
 Person1:      Come on man ! I even got dope and acid ! Try some ! 
 Person2: Do you really have all of these drugs ? Where do you get them from ? 
 Person1:      I got my connections ! Just tell me what you want and I ’ ll even give you one ounce for free . 
 Person2: Sounds good ! Let ’ s see , I want . 
 Person1:      Yeah ?  
 Person2:I want you to put your hands behind your head ! You are under arrest ! 
Solution: informal
Reason: Based on the conversation, we can see that there is a presence of exclamation which is not present in a formal discussion. Therefore this is an informal conversation

Now, solve this instance:  Person1:       How much do you pay wholesale for your products ? 
 Person2:We have a few different wholesale vendors , so our cost varies a bit over the fiscal year . But the difference is miniscule , a fluctuation of about 0.2 % . 
 Person1:        That must impact your bottom line at least a little bit , doesn't it ? After all , your sticker price is pretty much set in stone . How much do they go for retail ? 
 Person2:Retail price is 29.95 per unit . We take into consideration changes in supply cost when figuring this price . 
 Person1:        Is that including tax ? 
 Person2:No , that's the price before tax . The tax rate is varies from different marketing areas , so it is difficult for us to figure in . 
 Person1:        How much is your profit margin then ? 
 Person2:Our profit margin is in the neighborhood of 20 % .
