Using the Solow Model, If, in Time T = 50 $\bar { d } = 0.1$

Using the Solow model, if, in time t = 50, the capital stock is K₅₀ = 150, investment is I₅₀ = 15, and $\bar { d } = 0.1$ is the depreciation rate, capital accumulation is:

A) $\Delta K _ { 50 } = 5$
B) $\Delta K _ { 50 } = - 15$
C) $\Delta K _ { 50 } = 15$
D) $\Delta K _ { 50 } = 120$
E) $\Delta K _ { S 0 } = 0$
