Answer:

The percent change was 65.1% rounded to the nearest tenth.

Explanation:

The formula for percent change over a time period is:

#p = (N - O)/O * 100# where #p# is the percent change, #N# is the new value and #O# is the old value. In this case we are given the Old Value (25,800) and the New Value (42,600) so we can substitute these into the formula to calculate #p#, the percent change:

#p = (42600 - 25800)/25800 * 100#

#p = 16800/25800 * 100#

#p = 1680000/25800#

#p = 65.1# rounded to the nearest tenth.
