+1832 In this problem, part (b), why the answer is $100,000 + $100 x !
this 100,000 comes from were !
+129852 We have these points on the total cost graph (0, 100000) and (1000, 200000).....the slope of this line =
[200000 - 100000] / [ 1000 - 0] = 100000/1000 = 100
So....the equation of the line can be found using the point-slope form :
y - 100000 = 100[x - 0] simplify
y = 100x + 1000000
+33661 The y-axis is not in dollars, it is in 10^4 dollars. Look at the x10^4 in brackets after the word Dollars.
So the y- intercept isn't $10 it's $10*10^4 or $100000
+1832 Yes Alan, I know this, but the answer must be 100x , how did he find the answer 100000 + 100x
