A binary star system is composed of two stars (one blue,one red) that orbit a common point: the center of mass of the system.The distances from the stars to the center of mass might be labeled r_blue and r_red.The sum of the masses of the stars is M_blue + M_red = 3.70 $\times$ 10³³ kg.If it is known that r_blue = 2/5 r_red,what is M_red?

A) 1.06 $\times$ 10³³ kg
B) 2.64 $\times$ 10³³ kg
C) 1.48 $\times$ 10³³ kg
D) 2.22 $\times$ 10³³ kg
