If it was one quarter of the price, you multiply 1000 by 0.25 (1/4) to get 250 a month.
Well you know that $85 is 100% then half of that is 50% and I guess find 15% and add all of it to get 265%
If the functions are inverses, then f(g(x)) = x.
A.
The functions are inverses of each other.
B. The domain of f(x) = x≠3. The domain of g(x) is x≠0.
The domain of f(g(x)) is (-∞, 0) ∪ (0, ∞).
The domain of g(f(x)) is (-∞, 3) ∪ (3, ∞).
0,001 is the same 1/1000
The "percent version" of this number could be 0,1/100 or 0,1%
