I would say Sir/ma'am it seems that we are out of stock on that certain item. You can order online the item that you want. If not then can I have your name or phone number to tell you when we have that item again.

Answer:
$30,000
Explanation:
Opportunity costs refers to the incomes or benefits a person, business or investor loses or forgone when one alternative is chosen over another.
Since Kelvin will lose earnings of $30,000 a year from a full-time job if Kevin decides to attend college, this $30,000 a year is therefore the opportunity cost.
 
        
             
        
        
        
Display rules indicate such things as when to touch and where, when to smile and when to frown, and whether loud talking and expansive gestures or quietness and controlled movements should be used.  All cultures have these and they typically vary even just slightly from one another. These are instilled in us from the beginning and let us know what behavior is acceptable and when. Cultural differences allow people to work together and bounce ideas off of one another, but they most also know how to appropriately interact with different cultures.
