The function c(n) below relates the number of bushels of apples picked at a pick- your-own orchard to the final cost for the apples.
It takes as input the number of bushels of apples picked after paying an entry fee
to an orchard, and it returns as output the cost of the apples (in dollars).
c(n) = 15n + 30

N(c) = (c-15)/20

Step-by-step explanation:

C(n) = 20n + 15  

y = 20n + 15  

20n = y - 15

n = (y - 15)/20

step-by-step explanation:

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
