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 ) = 0.193 t ^ { 3 } - 3.88 t ^ { 2 } + 15.9 t + 370

and

M ( t ) = 0.033 t ^ { 3 } - 0.21 t ^ { 2 } + 1.7 t + 171

Where t represents the year, with t = 0 corresponding to 2000.

Find and interpret

( N + M ) ( t )

.

A)

( N + M ) ( t ) = 0.226 t ^ { 3 } + 4.09 t ^ { 2 } - 17.6 t - 541

, which represents the total number of Navy and Marines personnel combined.
B)

( N + M ) ( t ) = 0.226 t ^ { 3 } + 4.09 t ^ { 2 } + 17.6 t + 541

, which represents the total number of Navy and Marines personnel combined.
C)

( N + M ) ( t ) = 0.226 t ^ { 3 } - 4.09 t ^ { 2 } - 17.6 t - 541

, which represents the total number of Navy and Marines personnel combined.
D)

( N + M ) ( t ) = 0.226 t ^ { 3 } - 4.09 t ^ { 2 } + 17.6 t + 541

, which represents the total number of Navy and Marines personnel combined.
E)

( N + M ) ( t ) = 0.226 t ^ { 2 } - 4.09 t ^ { 3 } - 17.6 t + 541

, which represents the total number of Navy and Marines personnel combined.
