Multiple Choice

Solve for the indicated variable.
- $I = \frac { \mathrm { w } } { \mathrm { P } } \left( 1 - \mathrm { e } ^ { - \mathrm { as } / 3 } \right)$ , for $\mathrm { s }$

A) $s = - \frac { 3 \ln \left( 1 - I P _ { W } \right) } { a }$
B) $s = - \frac { 3 } { a } \ln \left( 1 - \frac { \mathrm { IP } } { \mathrm { w } } \right)$
C) $\mathrm { s } = \frac { \mathrm { IwP } \cdot \ln ( 1 - \mathrm { a } ) } { 3 }$
D) $\mathrm { s } = \frac { 3 \cdot \ln ( 1 - \mathrm { a } ) } { \mathrm { IwP } }$
