This was a long frustrating challenge...I really felt they both should have mastered 2 careers, but too many things did not go my way. Ah well. In the end the wife had 19 traits, she was a very interesting sim.
Both Sims mastered 1 career and made it to level 7 of a second career. 1200X2 + 200X4 = 3200
They earned 49 career rewards 49 X .05 =2.45 + 1 =3.45
3200 X 3.45 = 11040
