I have successfully located my login information and requested my access code. I hope to find information about assignments and due dates.

There are 2 questions in this document, accompanied by some instructions.

Copy this document into a word processor or text editor.

Answer the two questions posed in this document, inserting your answers, confidence assessments and self-critiques as explained.

Solutions are given, but don't look at the solution to a question or problem until you have entered your answer.

You will probably find that you can answer many of these questions without writing anything down.

It is often helpful to sketch, doodle, jot down ideas, do calculations, organize and test ideas on paper. On those problems where you cannot arrive at an answer 'in your head', is recommended that you work out your solutions on paper.

When appropriate, you will later be encouraged to use a calculator to do any arithmetic you cannot do mentally. However the calculator is not appropriate to the questions that appear on this document. Put the calculator aside and think through these questions.

When you are finished you will submit your work according to the instructions at the end of this document.

It is important that all the information in documents of this nature be submitted, so that all the information ends up posted at your page.

When submitting documents, do not delete anything from the original document. Insert your answers, questions, comments, etc. as indicated, but do not otherwise change the original document.

Question: `q001. If you are earning money at the rate of 8 dollars / hour and work for 4 hours, how much money do you make during this time? Answer in such a way as to explain your reasoning as fully as possible. A solution to this problem appears several lines below, but enter your own solution before you look at the given solution.

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution: (type in your solution starting in the next line)

8 dollars/hour*4 hours= 32 dollars

If someone makes eight dollars every hour and works for four hours, then their total earnings are eight multiplied by the number of hours they worked. It also makes sense when looking at units because multiplying dollar/hour by hours cancels out hours and leaves you with just dollars.

confidence rating #$&*: (Type in a number from 0 to 3, indicating your level of confidence in your solution.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

3 means you are at least 90% confident of your solution, or that you are confident you got at least 90% of the solution

2 means that you are more that 50% confident of your solution, or that you are confident you got at least 50% of the solution

1 means that you think you probably got at least some of the solution correct but don't think you got the whole thing

0 means that you're pretty sure you didn't get anything right)

My level of confidence was a 3.

.............................................

Given Solution: 8 dollars / hour means '8 dollars per hour', indicating that for every hour you work you earn 8 dollars. If you work for 4 hours, then if you earn 8 dollars for every one of those hours you earn 4 * 8 dollars = 32 dollars.

Self-critique (if necessary): (If you believe your solution matches the given solution then just type in 'OK'.

Otherwise explain in your own words how your solution differs from the given solution, and demonstrate what you did not originally understand but now understand about the problem and its solution.)

I think my solution matches the given solution, but I believe the given solution was probably stated more clearly and easier to understand.

------------------------------------------------

Self-critique Rating: (If you believe your solution matches the given solution then just type in 'OK'.

Otherwise evaluate the quality of your self-critique by typing in a number between 0 and 3.

3 indicates that you believe you have addressed all discrepancies between the given solution and your solution, in such a way as to demonstrate your complete understanding of the situation.

2 indicates that you believe you addressed most of the discrepancies between the given solution and your solution but are unsure of some aspects of the situation; you would at this point consider including a question or a statement of what you're not sure you understand

1 indicates that you believe you understand the overall idea of the solution but have not been able to address the specifics of the discrepancies between your solution and the given solution; in this case you would normally include a question or a statement of what you're not sure you understand

0 indicates that you don't understand the given solution, and/or can't make a reasonable judgement about whether or not your solution is correct; in this case you would be expected to address the given solution phrase-by-phrase and state what you do and do not understand about each phrase)

My self-critique rating would be a 3.

Question: `q002. If you work 12 hours and earn $168, then at what rate, in dollars / hour, were you making money?

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution: (type in your solution starting in the next line)

168 dollars/12 hours = 14 dollars/hour. If someone makes a total of 168 dollars and worked for 14 hours, then in order to find out how much money they make her hour you just divide the amount of money by the total hours.

confidence rating #$&*: (Type in a number from 0 to 3, indicating your level of confidence in your solution.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

3 means you are at least 90% confident of your solution, or that you are confident you got at least 90% of the solution

2 means that you are more that 50% confident of your solution, or that you are confident you got at least 50% of the solution

1 means that you think you probably got at least some of the solution correct but don't think you got the whole thing

0 means that you're pretty sure you didn't get anything right)

My level of confidence is a 3.

.............................................

Given Solution: $168 earned in 12 hours implies that $168 / 12 = $14 were made per hour, so the rate is $14 / hour.
