Question 1190145
<font color=black size=3>
x = number of years
y = population in thousands


The gap from 1803 to 1820 is 1820-1803 = 17 years.



Plug in x = 17 to find the y value
y = a*b^x
y = 500*(1-0.40)^x
y = 500*(0.60)^x
y = 500*(0.60)^17
y = 0.084633 approximately


y is the population in thousands, so multiply that approximate result by 1000
1000*0.084633 = 84.633
That rounds to 85


Answer: 85
