It is hard to choose an item !!

 

It is hard to choose an item......!!

    Every time We have opportunity cost ..

 Whenever we go the shop.. Wherever we go..

 What is the opportunity cost?

 It has something to do with choosing one product or service instead of another.

The item that you don't pick is opportunity cost.

We might not often realize it.
but we experience it every day.

 I went to the department store wth my freinds last week , I saw a beautiful shirt that is attracted to my eyes.

 It was so expensive..

Instead of it , Other shirt is good looking.

 It was lower price than first thing

I picked the next shirt . so it is the opportunity cost.

 Opportunity cost can also be an activity you don't choose to do during the day.

When we decide to go to the movies instead of going shopping

Then the opportunity cost is going shopping.

About a bottle with a message!

Sometimes in movies and books, we have often seen a bottle with a message.
Did people ever actually use bottles in this way?
Surprisingly, they did!
Queen Elizabath I employed an official.
His job was to open bottles with messages.
The messages were sent from the British navy when they needed help.
Elizabeth was so serious about this job. She made it a crime for anyone else to open found bottles.
Famous American statesman and scientist, Benjamin Fraklin, also used massages in bottles.
His purpose was to draw a map of the ocean currents.
He did this by dropping bottles with messags into the Gulf Stream.
When people found and returned them, he was able to work out the exact local for his map.
Don't you think it was a clever method?
