Restaurants normally add a 15% tip when charging a meal on a credit card. What would be the total amount charged if the cost of the meal without tip is $49?

$56.35

Step-by-step explanation:

15% of $49 = $7.35

$7.35 + $49(cost of meal without tax)

$7.35 + $49 = $56.35

i do not know this sorry : (

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.
