Answer:

Rick had a 19.0% increase in weight rounded to the nearest tenth of a percent.

Explanation:

To find the percent change over time you use the formula:

#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 provided the New Value (188) and the Old Value (158). We can substitute this into the formula and calculate the percent change, #p#:

#p = (188 - 158)/158 *100#

#p = 30/158*100#

#p = 3000/158#

#p = 19.0%# rounded to the nearest tenth
