Answer:
C. 6 times as many as c is 72
Step-by-step explanation:
You want to know if c = 12, which statement is true.
We can substitute 12 for c in each expression and write it as a math equation. That makes it easier to see if it is true.
12 = 5×4
12 = 20 . . . . . false
27 = 12×3
27 = 36 . . . . . false
6×12 = 72 . . . . . TRUE
8 + 12 = 15
20 = 15 . . . . . false
