Answer:
f(z) = 86.(0.169)z
Step-by-step explanation:
Let's call
We have the growing function f(x) = 86.(1.18)x. If we want to write f in terms of z, we need to consider that x = z/7, since there are 7 days in each week. Then,
86.(1.18)x = 86.(1.18)z/7 = 86.(0.169)z
f(z) = 86.(0.169)z
What you have is a valid ratio in theory, but it might be easier to understand if it were simplified to integers:
78:13:65
It also depends on what your teacher is asking of you.
Well, I am not exactly sure if this is what your asking but one foot is twelve times the size of a foot.
