Kathy has $100 to spend on her shopping trip. she needs to buy jeans, which are $28.50 each and shirts cost $18.50 each. write an inequality to show how many jeans, j, and shirts, s, she can buy and stay within her budget?

28.50j+18.50s ≥ 100

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.
