Solve for the Indicated Variable $$A = \frac { B s } { 1 - ( 1 + z ) ^ { - t ^ { \prime } } } \text { for } t$$

Multiple Choice

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

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