Suppose There Are L₀ People in the World Today $\bar { n }$

Suppose there are L₀ people in the world today. If the population growth rate equals $\bar { n }$ , then in 50 years, the world population will be:

A) $L _ { 50 } = L _ { 0 } \bar { n } ^ { 50 }$
B) $L _ { 50 } = L _ { 0 } ( 1 + \bar { n } ) ^ { 50 }$
C) $L _ { 50 } = L _ { 0 } \Sigma _ { T = 0 } ^ { 50 } ( 1 + \bar { n } ) ^ { t }$
D) $L _ { _ { 50 } } = L _ { 0 } ( 1 + \bar { n } ) \times 50$
E) $L _ { _ { 50 } } = L _ { 0 } ( 1 + \bar { n } ) \div 50$
