Answer:

The initial population at the beginning of the 10 years was 129.

Step-by-step explanation:

The population of the village may be modeled by the following function.

P(t) = P_{0}e^{rt}

In which P is the population after t hours, P_{0} is the initial population and r is the growth rate, in decimal.

In this problem, we have that:

P(10) = 158, r = 0.02.

So

158 = P_{0}e^{0.02*10}

P_{0} = 158*e^{-0.2}

P_{0} = 129

The initial population at the beginning of the 10 years was 129.

Answer:

Step-by-step explanation:

The formula representing the population growth after t years can be expressed as

A = P(1+r/n)^nt

Where

A is the population of the village after t years.

P represents the initial population of the village at the beginning of the 10 years.

r represents population growth rate

n represents the number of times that the population was compounded in each year.

From the given information,

A = 158

r = 2% = 2/100 = 0.02

t = 10 years

n = 1 because it was compounded continuously each year.

Therefore

158 = P(1+0.02/1)^1×10

158 = P(1.02)^10

P = 158/(1.02)^10 = 129.615

Approximately 130 to the nearest whole number.
