Today, 5 friends went out for lunch. Their total bill was $35.38, including tax and gratuity. One of them ordered only soda and needed to pay only $1.58. The
other 4 friends ordered the same dally special. How much did each of the other friends need to pay?

35.38 - 1.58 = 33.80

33.80 divided by 4 = 8.45

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

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.
