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).
