Multiple Choice

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

A) $w = \frac { 3 \cdot \ln ( 1 - a ) } { I t P }$

B) $w = - \frac { 3 } { a } \ln \left( 1 - \frac { \mathrm { IP } } { \mathrm { t } } \right)$

C) w $= \frac { \mathrm { ItP } \cdot \ln ( 1 - \mathrm { a } ) } { 3 }$

D) $w = - \frac { 3 \ln ( 1 - \mathrm { IPt } ) } { \mathrm { a } }$
