Turn the information into coordinate points.
Point = (time, population)
Point 1 = (1985, 45000)
Point 2 = (2004 , 26000)
Find the slope between these points using the formula
( Slope)—> m = (y2 - y1) / (x2 - x1)
26000-45000/2004-1985=-19000/19= -1000
Average rate of change is decrease of 1000 sea lion per year
I hope that helped

Answer:
Therefore 164 children and 89 adults swam at the public pool that day.
Step-by-step explanation:
Given that,
253 people used the public swimming pool.
The daily prices for children are $1.50 and for adults are $2.25.
Let the number of children be x.
Then number of adult is (253-x)
The total money collect on that day is ![=\$[(1.50\times x)+2.25(253-x)]](https://tex.z-dn.net/?f=%3D%5C%24%5B%281.50%5Ctimes%20x%29%2B2.25%28253-x%29%5D)
![=\$[1.50x+569.25-2.25x]](https://tex.z-dn.net/?f=%3D%5C%24%5B1.50x%2B569.25-2.25x%5D)
![=\$[569.25-0.75x]](https://tex.z-dn.net/?f=%3D%5C%24%5B569.25-0.75x%5D)
According to the problem,





Therefore 164 children and (253-164)=89 adults swam at the public pool that day.
