It is given in the question that ,
The price per share of a stock changes by -$4.50 on each of 5 consecutive days.And the starting price of the share is $67.50.
Therefore, after first day, the price of share is
[tex]67.50-4.50 = $63[/tex]
Price of share after second day
[tex]63-4.50 = $58.50[/tex]
Price of share after third day is
[tex]58.50-4.50 = $54[/tex]
Price of share after fourth day is
[tex]54-4.50 = $49.50[/tex]
And price of share after fifth day is
[tex]49.50-4.50 = $45[/tex]
And that's the price of the share after 5 consecutive days .
