Multiple Choice

Solve for the indicated variable.
- $A = \frac { W B } { 1 - ( 1 + z ) ^ { - s ^ { \prime } } }$ , for $\mathrm { s }$

A) $s = \frac { \ln A - \ln ( A - W B ) } { \ln ( 1 + z ) }$

B) $s = \ln \frac { W } { ( A - A B ) ( 1 + z ) }$

C) $s = \frac { \ln W } { \ln [ ( A - A B ) ( 1 - z ) ] }$

D) $s = \ln \frac { A } { ( A - W B ) ( 1 + z ) }$
