I NEED HELP ASAP PLEASE ANWSER Josh and his friends bought vanilla wafers for $4 per packet and chocolate wafers for $1 per packet at a carnival. They spent a total of $46 to buy a total of 28 packets of wafers of the two varieties.

Part A: Write a system of equations that can be solved to find the number of packets of vanilla wafers and the number of packets of chocolate wafers that Josh and his friends bought at the carnival. (4 points) Define the variables used in the equations. (2 points)

Part B: How many packets of chocolate wafers and vanilla wafers did they buy? (2 points) Explain how you got the answer and why you selected a particular method to get the answer. (2 points)

need points to ask question

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.  

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

answer4 to the second power is 16

and 4 to the third power is 64,
