Answer  
Find out the  percent error in Annie's estimate .
To prove 
Formula

As  error = approx value -  exact value 
As given
Annie estimates that the height of a bookcase is 78.25 in. 
The actual height is 75.50 in. 
approx value = 78.25 in. 
actual value = 75.50 in. 
error = 78 .25 - 75 .50
         = 2.75 
put in the formula 


Percentage error = 3.64 % (approx)
Therefore the Percentage error be 3.64 % (approx).
