Part 1- My Solution

Part A

=80000*1.035+10000=92800

=92800*1.035+10000=106048

=106048*1.035+10000=119759.7

Part B

=80000*1.042=83360

=83360*1.043=86944.48

=86944.48*1.042+30000=120596.1

Part C

High

(6.03%-11.64%+19.13%+2.17%+21.74%)/5=7.49%
80000*1.075*1.075*1.075+10000*1.075*1.075+10000*1.075+10000=131690

Low

(19330.81-20762)=-6.9%
80000*0.931+10000=84480

84480*0.931+10000=88650.88

88650.88*0.931+10000=92533.97

Part 2- Visual Representations

Part 3- Justification

The known results of the current three plans are: plan A is a little bit, plan B is just a little more secure, and the best result of plan C is enough and a lot more, but there is a high possibility that there will be a lot more. In general, the easiest, safest and safest solution is B, but C has a higher probability. To sum up, I choose B, which is more suitable for me. It is not only safe, but also will meet the requirements, not to mention that I am very unlucky.

Part 4- Collaboration and Contributions

Answer the following questions:

1. How did you find working with your?

I think I am a pioneer, first calculation and trial and error.

2. How did you contribute to the group? And how did others in the group contribute to your learning?

Perform advanced calculations and trial and error to help others learn. There will also be people who can do it faster than me, and I will learn from it.

3. Did you use any other the solutions proposed by your group? Why or why not?

It is right to try, after all, people grow through constant trial and error and correction. why not? There is no harm.

4. How would you rate your ability to collaborate with others in your group on a scale of 1-4 (1 not good; 4- excellent)

I think they shoud 4.

Part 5- Core Competency Reflection

1. Competencies of Communication

As an active listener, I noticed that sometimes I inevitably make mistakes, but I will also actively correct and learn, and even take the initiative to find my own mistakes and correct them.

2. Collaborating

I can work with others to achieve goals.
I can identify differing viewpoints and respectfully disagree.
I can use constructive strategies to resolve misunderstandings and conflicts.

3. Critical and Reflective Thinking

I use evidence to make judgments or decisions as follows: sometimes I wonder if it is right or wrong, most of the time I make a judgment after reflection, and once even the teacher said that I was wrong on a question Yes, I did not follow blindly, not that I think what the teacher said must be right or wrong, but just my own reflection, and the result is that I also came to the conclusion after checking that the teacher was wrong.

4.Creative Thinking

When good ideas don’t seem to come to me, I’m helping myself calm down or creating space in my mind to conceive and create, such as when I did a question and thought “Wow! This question is so complicated and difficult to solve” Ah!” But after I calmed down, I had a flash of inspiration, a new way of thinking, and suddenly felt that this topic was very simple.
