If C + D = 12 and C and D are positive integers, which of the following is a possible value for 5C + 8D?	Select the correct option:
A) 111  B) 121  C) 150  D) 171  E) 180
c + d = 11   5c + 8d = 5c + 5d + 3d = 5(c+d) + 3d = 60 + 3d=D=30   D=30   c+d=12=150+30=9=150=12-30=-18   150=-18   5150 + 8D=5(-18)+8(30)=-90+240=
