Solve the formula $V = 3 ( r - I ) a$ for the variable $r$ .
A) $r = \frac { 3 V } { a } - 1$
B) $r=\frac{V+1}{3 a}$
C) $r= \frac { V } { 3 a } - 1$
D) $r = \frac { 3 V } { a } + 1$
E) $r = \frac { V } { 3 a } + 1$

To solve for $r$, you first divide both sides by 3a to get $r - I = \frac{V}{3a}$. Then, add $I$ to both sides to isolate $r$, resulting in $r = \frac{V}{3a} + I$. Since $I$ represents 1, the correct formula is $r = \frac{V}{3a} + 1$.

Solve the Formula V=3(r−I)aV = 3 ( r - I ) aV=3(r−I)a

Solve the Formula $V = 3 ( r - I ) a$
