Solve the formula for the indicated variable.
-$P = 21 + 2 w$, for 1
A) $l = \frac { P } { 2 } - 2 w$
B) $I = \frac { P } { 2 w + 2 }$
C) $l = \frac { P - 2 w } { 2 }$
D) $I = P - 2 w - 2$

The correct rearrangement of the formula $P = 21 + 2w$ to solve for $l$ seems to be a misunderstanding in the question, as $l$ is not present in the original equation. Assuming the goal is to solve for $w$, option C correctly isolates $w$ on one side: $w = \frac{P - 21}{2}$. However, given the options and the apparent typo, C is the closest in form, correctly showing the process of isolating a variable (though it mistakenly uses $l$ instead of $w$, and misinterprets the constant as $21$ instead of $2w$).
