Answer:
I think you mean the equation is

And you must find

Y=mx+b is slope intercept form
Answer:
True
Step-by-step explanation:
Okapi=o llama=l
o+l=450
3l=190+o
I cant remember how to work it out but if you have a graphics calculator you would open a calculator page, press Menu:3:1 (solve function) and type in those equations. It would look like this:
solve(o+l=450 and 3l=190o,o)
l=160 o=290
llamas are 160kg and okapis are 290kg. Hope that helped a bit :)
Production cost = one time cost + variable costs
Let the number of published books for equal production costs be n.
Using the first method:
production cost = 18,853 + 19.75n
Using the second method:
production cost = 64,853 + 8.25n
Now, we need the two production costs to be equal:
18,853 + 19.75n = 64,853 + 8.25n
Solve for n as follows:
18,853 + 19.75n = 64,853 + 8.25n
19.75n - 8.25n = 64,853 - 18,853
11.5n = 46000
n = 46000/11.5
n = 4000 books
