 Hello and welcome to the session. In this session we will discuss a question which says that Sam's grandfather gives him M dollars every week and his grandmother gives him M dollars every week. Sam wants to buy his favorite board game which costs $1 million. Will he be able to buy the game after two weeks if his grandfather gives him $20 and his grandmother gives him $30 every week. Now let us start with the solution of this question. Now in the question it is given that Sam's grandfather gives him M dollars and his grandmother gives him M dollars every week. So he gets a total of $20 plus M dollars every week. Now Sam wants to buy his favorite board game after. Now he has a total sum of M plus M dollars in one week. So in two weeks he will have a total of M into M plus M the whole dollars. Now his grandfather gives him $20 and his grandmother gives him $30 every week. So now we have M is equal to $20 and N is equal to $30. Now we will push the values of M and N in this expression and from here we can find the total amount that Sam has got after two weeks. So the total money in two weeks will be equal to 2 into M which is $20 plus M which is $30 the whole which is equal to 2 into $50 which is equal to $100. Now we know that cost of board game is equal to $120 but Sam has $100 after two weeks therefore he will not be able to buy the game and this is the solution of the given question. That's all for this session. Hope you all have enjoyed the session.
