Answer

(i) The statement is false. (ii) The correct statement would be: It is necessary to use the distributive property to solve $P=C + MC$ for $C$.

Work Step by Step

The equation has two terms that contain the variable C. This means that there is a need to combine them before you can isolate C on one side of the equation. Thus, to solve for C in the given equation, the distributive property must be used to find: $P=C + MC \\P=C(1+M) \\\dfrac{P}{1+M} = C$ Therefore, the given statement is false.
