population decreases by 15
population increases by 15
population decreases by 24

Answers

Population decreases by 15.

Birth rate means more population (positive), death rate means less population (negative), immigration means more (positive), and emigration means less (negative).  So, just add and subtract the appropriate numbers:

35\ people\ born-7\ people\ die+4\ people\ enter-17\ people\ leave=\\-15\ people

Negative 15 people means that the population decreases by 15.
