A Change in the Capital Stock, ÄK_t, Can Be Expressed $\bar { s }$

Multiple Choice

A change in the capital stock, ÄK_t, can be expressed as a function of the saving rate, $\bar { s }$ , output, $F \left( K _ { t } , \bar { L } \right)$
, the capital stock, K_t, and the depreciation rate, $\bar { d }$
, by:

A) $\Delta K _ { t } = \bar { s } F \left( K _ { t } , \bar { L } \right) + \bar { d } K _ { t }$
B) $\Delta K _ { t } = \bar { s } F \left( K _ { t } , \bar { L } \right) - \bar { d } K _ { t }$
C) $\Delta K _ { t } = \bar { d } F \left( K _ { t } , \bar { L } \right) - \bar { s } K _ { t }$
D) $\Delta K _ { t } = \bar { s } F \left( K _ { t } , \bar { L } \right) / \bar { d } K _ { t }$
E) $\Delta K _ { t } = F \left( K _ { t } , \bar { L } \right) - K _ { t }$
