To answer this problem you have to use a ratio, if it begins with 8:500, multiply 40 or 20,000/500 on both sides to get 320:20,000
X + 12 + X - 6 = X + 50
2X + 6 = X + 50
X = 44
44 + 50 = 94
To check you can substitute X into the problem.
44 + 12 = 56
44 - 6 = 38
44 + 50 = 94
56 + 38 = 94
94 = 94
#1 = 96
#2 = 162
There is 16 pirates per ship since there is 32 pirates in 2 ships. This means that you can multiply 16 by 6 and 16 by 12 to get your answers
The "line of best fit" is the result of a linear regression computation. If you have done that, you already know its equation.
If you have "eye-balled" the line into place, then you have to figure out its equation from points you read on the graph. We take a couple of the points to be ... (2001, 1700) and (2010, 2450)
The line through these points will have the equation
... y = (2450 -1700)/(2010 -2001)(x -2001) +1700
... y = (250/3)(x -2001) +1700
Putting x=2013 into this equation, we get ...
... y = (250/3)(2013 -2001) +1700
... = (250/3)(12) +1700
... y = 2700
The population is predicted to be 2700 in 2013.
