Initially, there were only 86 weeds in the garden. the weeds grew at a rate of 18% each week. the following function represents the weekly weed growth: f(x) = 86(1.18)x. rewrite the function to show how quickly the weeds grow each day.

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

step-by-step explanation:

the correct answer is $7.38
