A) Let x = cost of t-shirt:

x= 22.95-12.25

B) x = 22.95 -12.25 = 10.70

C) the t-shirt cost $10.70

your answer is d 2,500

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.
