$45

Step-by-step explanation:

Let the regular price be x

according to the question

the equation is

x×85/100=38.25

x×85/100=38.25

x=38.25×100/85

x=38.25×20/17

x=45

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.
