**Problem 1**

b) address why the periodic payment formula is appropriate to use here.

c)28973.12

e) address why the lump sum formula is appropriate to use here.

f)396,645.88

g)20,000.00

h) You should address why it makes sense that
20,000 can grow to 396,645.88 (use the length of time, the rate,
and relate to similar problems we've seen on compound interest...)

**Problem 2 **

b)You should address why the loan payment formula is appropriate to use here.

c)28.35

d)952

e)14.13

f) Notice that part d) divided by 120 would yield an answer
smaller than what you obtain in part e) and that if the calculation was
done this way, it would mean that the interest was the same each and
every month over the life of the loan.
You should relate this to the problems and
address why this is not the case.

g)437.88 (Hint: see the similar calculation from the condo
lab and our class work on the student loan statement)

h)514.12

i) You should address why it makes sense that when you pay extra
each month,
you end up paying less interest (514.12 as opposed to the original 952),
using your knowledge of how loans work.

k) You should explain why the loan payment formula is appropriate
to use in this case.

**Problem 3**
See the relevant web reading entitled "What is Math" that was a homework
reading for the Monday before the test and was listed on the review sheet.
Summarize one of the parables in your own words.

- quiz 1________ quiz 2________ quiz 3________
From the main WebCt page, click on the "grades and tracking info" link.
Click on "grades". Write down both quiz grades.

Cross out the lowest quiz grade, since the lowest quiz is dropped. Is your quiz average an A? - Have you been reading any messages from Dr. Sarah at least once a week? Dr. Sarah can track this on WebCT. Note that you should check the main web page before each class.
- Have you been turning in and receiving checks or checkpluses on assignments that are not graded numerically?
- Have you been participating in class and lab activities and adding to a professional classroom environment?

Write down all of your lab project grades from WebCT. (From the main WebCt page, click on the "grades and tracking info" link. Click on "grades") If you see the assignment on the WebCT "grades", but see --- or if you don't see the assignment header, than I haven't posted that assignment yet but will soon.

lab1 ____ lab2_____ lab3_____ lab4_____

Now cross out the lowest lab (just one!), and then take an average of the labs that remain. (ie add up the lab grades that remain, and then divide by the number of those labs that remain).

Add up parts A, B and C _______.

Since this is out of a total possibility of 60 points, divide this by 60 and then multiply by 100 to obtain your

This will be positive if you have less than 3.5 credit hours of absences, and negative if you have more than 3.5 credit hours of absences.

If all of your writing assignments and lab projects are turned in on time AND you have received at least 50% credit for all work, and you have turned in all but 3 of the other homework assignments on time, then fill in 1.5 into Part F. Otherwise you do not receive the on-time credit and so you should fill in 0 into Part F.

As a general rule of thumb for mathematics classes, on average, you can expect to spend about 2-3 hours outside of class per week reviewing material and class notes, 3-6 hours outside of class per week for homework assignments, and about 1 hour outside of class per week on checking the main web page and bulletin board. If you find that you are spending fewer hours than these guidelines suggest, you can probably improve your grade by studying more. If you are spending more hours than these guidelines suggest, you may be studying inefficiently; in that case, you should come see me.
