To simplify the expression \( c + 0.85c \), we can factor out \( c \):
\[
c + 0.85c = 1c + 0.85c = (1 + 0.85)c = 1.85c
\]
Thus, the expression \( c + 0.85c \) is equivalent to \( 1.85c \).
So the correct answer is:
**D. 1.85c**
\[
c + 0.85c = 1c + 0.85c = (1 + 0.85)c = 1.85c
\]
Thus, the expression \( c + 0.85c \) is equivalent to \( 1.85c \).
So the correct answer is:
**D. 1.85c**
