Directions for learner
This performance assessment task has four sections: GPA Calculation, temperature conversions, solving equations, and compounding interest. You must satisfactorily complete all sections to gain credit for this assignment.
Section 1: Computation of Grade Point Average (GPA) (Using data in your education)
To compute the GPA for the quarter, each letter grade is converted to the grade point equivalent listed in your course syllabus, section entitled as Berkeley College Grading System. Then, that grade point is multiplied by the number of credits designated for the course. This procedure is followed for each course.
Next, the number of grade point equivalents for all courses is added. That total is then divided by the total number of credits attempted for the quarter. The result is the quarter GPA.
Your task is to compute your Grade Point Average (GPA) for your first quarter at Berkeley College if you received the following grades as described below:
COURSES TAKEN  NUMBER OF CREDITS  GRADES RECEIVED AT THE END OF THE QUARTER 
Financial Accounting I  4 Credits  B+ 
Business Organization & Management  4 Credits  C+ 
English 105  4 Credits  B 
College Algebra  4 Credits  C 
A) Use the above table to calculate the student‘s first quarter Grade Point Average (GPA) at Berkeley College.
B) In order for full time students to be eligible for the President list, they must have a GPA of 4.0 for the quarter. Based on your GPA calculation, were you eligible for the President’s list? What grade did you need to get in all your classes to be eligible for the President’s list?
C) In order for full time students to be eligible for the Dean’s list, they must have at least a GPA of 3.5 for the quarter. Based on your GPA calculation, were you eligible for the Dean’s list? What grade (s) would you need to change, if any, to meet the criteria for the Dean’s list?
Section 2: Temperature Conversions
Facts:
Countries That Use Celsius Today
Countries that Do Not Use Celsius

In this section, you will use an external source of information such as the internet to get six different high temperatures for six different locations. The first three data you gather will be the temperature using the Fahrenheit scale (F). Then you will convert the Fahrenheit temperature (F) to Celsius temperature (C) to complete table 1.
The next three data you gather must be the temperature using the Celsius temperature (C). Then you will convert the Celsius temperature (C) to Fahrenheit temperature (F) to complete table 2.
You will need to know the following formula:
Celsius temperature is five ninths the difference of Fahrenheit temperature and thirtytwo
C = (5/9)(F32)
First, fill in your data in Fahrenheit temperature in this table, except for the last column where you need to convert from Fahrenheit temperature to Celsius temperature. (WORK MUST BE SHOWN).

Second, fill in your data in Celsius temperature in this table, except for the last column where you need to convert from Celsius temperature to Fahrenheit temperature. (WORK MUST BE SHOWN).
Use F = (9/5) C + 32

Section 3: Solving equations (Using data to make your best shopping decision)
 If you have or had a job, write down the approximate net amount that you get (got) paid each week. If you never had a job make an estimate of how much you could get paid working in your spare time.
 Assume that you will save $37.50 each week from your net pay. Calculate the percent of your net weekly pay that you will be saving.
 Decide on an item that you would like to buy (that usually cost over $299.99). Conduct a search to find the best price for this item. State the item, the sale price and the Web site where you found the item for this particular price.
 NJ has a 7 % sales tax rate and the NY sales tax rate is 8 ¼ %.
 In what state do you usually do most of your shopping?
 Calculate the final, aftertax, price that you will pay for the item.
 Assuming that you already had $50 saved, substitute all the known quantities into the formula that follows to create an equation with one unknown value. Solve the equation and determine the minimum number of weeks that you will need to save in order to have enough money to purchase this item.
(Final Price) = (Weekly Savings) (number of weeks) + (Amount already saved).
Note the minimum number of weeks must be a whole number correctly.
Section 4 Using data to make your best investment decision
The average total monetary gifts that high school graduates received range from $500 to $6,000 inclusively.
To celebrate your high school graduation, you received several monetary gifts from your family and friends. Assume that the total amount of monetary gifts you received fall between the stated range.
a) How much monetary gift did you receive?
b) You decided to invest your money by opening a 2year Certificate of Deposit (CD). Search the following website to investigate which bank will give you the best offer. Identify the bank and describe the offer by identifying the interest rate, minimum amount required and the method of compounding. http://cdrates.bankaholic.com/
c) How much money would you have in your account at the end of the 2year period?
d) How much interest would you receive on your investment?
