Ответ:
m(x) = 20000(0.97)^x
Step-by-step explanation:
Given that :
Initial population, population in 1990, P = 20,000
Rate, r = 3% = 0.03
Number of visitors to the museum x years after 1990
Since population decreases, Decay formula
m(x) = Initial population * (1 - r)^x
m(x) = 20000(1 - 0.03)^x
m(x) = 20000(0.97)^x
