The average score for the entire year is 88.44444, so by rounding down the answer is 88%
Find the slope of the line connecting (1990,435000) and (2005,482300):
482300-435000 47300
m = ----------------------- = ---------------- = 3153/yr (approx)
2005 - 1990 15 yr
Use the point-slope formula to find the equation of this str. line:
y-435000 = (3153/yr)(x-1990)
The year 2020 is 30 years after 1990. Thus, the expected pop in 2020 is
given by y-435000 = 3153(30) = 94590, so that y = 529590.
Both the x and y have to be greater than zero so you need to add two inequalities, x>0, y>0
Answer:
95
because what is 95 times 10.8 if you multiply that you will get 1026
Also you get 95 by dividing 1026 by 10.8
