You and your friends have pooled your money and have $12 to spend on lunch . You agree to share a large fry and buy sandwiches with the rest of the money . If the price of a large fry is $1.22 and the price of a sandwich is $0.89 , how many sandwiches can you buy ?

You can buy 12 sandwiches.

Step-by-step explanation:

You have to take off the price of the large fry from the amount of money you can spend. So $12-$1.22=$10.78

Then you divide 10.78 by 0.89 (the price of one burger.)

You get a decimal, but you can't buy half of a burger so you round down and get 12.

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.
