three significant digits.

Question

The population of a certain geographic region is approximately 117 million and grows continuously at a relative growth rate of 1.51%. What will the population be in 4 years? Compute the answer to three significant digits.

Answer 1

P = 117(1.0151)⁴

P ≈ 117(1.06178188)

P ≈ 124.228480

 

Since the starting population was given only the the nearest million, the population would be 124 million.
