The percentage change was 10.7% rounded to the nearest 1/10th percent.

Explanation:

The formula for calculating the percentage change of something 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 problem we are told the old value is $27.10 and the new value is 30.01 so we can substitute these for #O# and #N# in the formula and calculate the percentage change:

#p = (30.01 - 27.10)/27.10 * 100#

#p = 2.91/27.10 * 100#

#p = 291/27.10#

#p = 10.738# or #10.7# rounded to the nears 1/10 percent.
