Answer is C.

2H+5C=21-----> (1)
3H+6C=27.60 --->(2)
You don't need to solve since both statement 1&2 combined provide enough information to solve the question.

Both statements gives us two different equations to find two unknowns.

Hence (C)

1) 5C + 2H = \$21 (N/S on it's own)
2) 6C + 3H = \$27.6 (N/S on it's own)

6C+3H=27.6
-5C+2H=20.0
C+H=\$6.6 ----> Answer Choice C, Together sufficient
