The California Tiger Salamander is an endangered species, which decreases at the rate of 4.6% per year in a habitat that current

stellarik [79]

Answer:

Population after 4 years = 49 (nearest unit)

Population after 5 years = 47 (nearest unit)

Step-by-step explanation:

Yearly decrease = 4.6%

Decrease factor (what's left) = (100-4.6)% = 0.954

Current population, P = 60

population after n years = P(0.954)^n (to the nearest unit)

Population after 4 years = 60(0.954)^4 = 49.7 = 49 (nearest unit)

Population after 5 years = 60(0.954)^5 = 47.4 = 47 (nearest unit)
