Answer: P = Po ( 1 + 0.075)
Step-by-step explanation: let Po = initial population
P = final population.
The increase in population is by 7.5%, which implies that if the initial population Increases by 7.5%, we would have a new (current) population.
Final population = initial population + increament of initial population.
Where increment of initial population = 7.5% of Po = 0.075 Po
P = Po + 0.075Po
P = Po ( 1 + 0.075)
