The total numbers of Navy personnel N (in thousands) and Marines personnel M (in thousands) from 2000 through 2007 can be approximated by the models N(t)=0.1943-7.882+12.9t+375 and M(t) = 0.0313-0.25+6.7t+173 where t represents the year, with t = 0 corresponding to 2000. Find and interpret (N-M)(t). O (N-M)(t)=0.16313+7.632-6.2t+202, which represents the difference between the number of Navy personnel and the number of Marines personnel. O(N-M)(t)=0.1633-7.632-6.2t-202, which represents the difference between the number of Navy personnel and the number of Marines personnel. O (N-M)(t)=0.163+3 +7.63+2+6.2t+202, which represents the difference between the number of Navy personnel and the number of Marines personnel. O (N-M)(t)=0.16313-7.632-6.2t+202, which represents the difference between the number of Navy personnel and the number of Marines personnel. O (N-M)(t)=0.1633-7.63+6.2t+202, which represents the difference between the number of Navy personnel and the number of Marines personnel.
