The Solution:
The difference of c and 7 is either:
[tex]\begin{gathered} c-7\text{ } \\ \text{ or} \\ 7-c \end{gathered}[/tex]
Multiplying the result by 10, we get
[tex]\begin{gathered} 10(c-7) \\ \text{ or} \\ 10(7-c) \end{gathered}[/tex]
We are asked not to simplify any part of the expression.
So, the correct answer is:
[tex]\begin{gathered} 10(c-7) \\ or \\ 10(7-c) \end{gathered}[/tex]
