Answer:

There was a -92.7% change in the number of cards in Shannon's collection.

Explanation:

The percentage change can be calculated using the formula:

#p = (N - O)/O * 100# where #p# is the percentage change, #N# is the New Value and #O# is the Old Value. Substituting for the New Value (#165 - 153 = 12#) and the Old Value (165) we can calculate the percentage change:

#p = (12 - 165)/165 * 100#

#p = (-153)/165*100#

#p = (-15300)/165#

#p = -92.7# rounded to the nearest tenth.
