There are 3 items you wish to buy. These items cost 4.99 15.99 and 30.99 you have two options option a: each item is discounted 10% option b: the most expensive item is discounted 20% the other items will cost their regular price. Which option is the cheapest

option 2 is the cheapest

Step-by-step explanation:

Option 1 :

10% of 4.99 = 0.499

10% off 4.99 =

4.99 - 0.499 = 4.491

10% of 15.99 = 1.599

10% off 15.99 =

15.99 - 1.599 = 14.391

10% of 30.99 = 3.099

10% off 30.99=

30.99 - 3.099 = 27.891

Total = 4.491 + 14.391 + 27.891 = 46.773

Option 2 :

Most expensive item = 30.99

20% of 30.99 = 6.198

20% off 30.99=

30.99 - 6.198 = 24.792

Total = 24.792 + 15.99 + 4.99 = 45.772

Therefore, option 2 is cheaper by 1.001.

Hope this helped :)

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.
