Different breeds of dogs get older at different rates in “dog years.” Livonian wolfhounds age 7 times as fast as humans, whereas Khazarian terriers age 5 times as fast and Akkadian retrievers age 4 times as fast. If Dan bought a newborn Akkadian on January 1, 2008, a newborn Khazarian 1 year later, and a newborn Livonian 1 year after that, in what year will the sum of the dog-year ages of the Akkadian and the Khazarian first be exceeded by twice the age of the Livonian in dog years, rounding all ages down to the nearest integer?  Choose the correct choice: A) 2015 B) 2014 C) 2013 D) 2016 E) 2017
chart starting at 2010:   A+K=13   L=0.   Then I added 9 to a+k for each year and 14 to L for each year.   2011:AK=22 L=14   2012:AK=31 L=28   2013:AK=40 L=42   thus, 2013 is the correct answer. =&gt; 2013
