Do you have any PROBLEM with Task 3? April 2, 2012

Filed under: Project — computer_resources @ 4:02 am

I am still worrying that there might some of you finding it’s difficult to find the NET PROFIT.

As I explained in the classroom, in the TASK 3; it is given that:

NET PROFIT = TOTAL SALES – TOTAL EXPENSES

I explained to you that you need to find NET PROFIT for EACH RECIPE.

Let say, you have CHOCOLATE CUPCAKES, so you need to find NET PROFIT FOR CHOCOLATE CUPCAKES.  (This is only an example)

Below is the diagram of TOTAL EXPENSES of Chocolate Cupcakes for 1 month.

So, How to find TOTAL SALES & NET PROFIT?

To find TOTAL SALES, don’t just put a BIG ASSUMPTION on the amount.  Here are the clues:

If you look on the diagram above, the TOTAL EXPENSES= $54.20  (This is the amount that you have spent on buying ingredients of 1 recipe FOR ONE MONTH)

Think LOGICALLY!!  one month = 4 weeks. You approximately divide TOTAL EXPENSES, $54.20 by 4 weeks = $13.55 per week.

Let say in week 1, you sell your product (Chocolate Cupcake) in a BOX every MONDAY, WEDNESDAY, and SATURDAY.  Below is the calculation:

1 box (consists of 2 cupcakes) costs $1.50.  You sell 5 boxes per day. 

  • If 5 boxes were sold, you will get $7.50 per day.
  • If only 3 boxes were sold, you will get $4.50 per day.
  • IF you refer to the table above, it is actually calculated such as:
  • MONDAY:5 boxes were sold  X  $1.50 =  $7.50
  • WEDNESDAY: 5 boxes were sold  X  $1.50 =  $7.50
  • SATURDAY: 5 boxes were sold  X  $1.50 =  $7.50

 **$7.50 + $7.50 + $7.50 = $22.50 for WEEK 1  (You also need to do estimation for the rest of the weeks)

NOW!! Total up the TOTAL SALES OF ALL WEEKS For Chocolate Cupcakes

Week 1 = $22.50

Week 2 = $18.00

Week 3 = $13.50

Week 4 = $22.50

You sum them up, =$76.50

*******

FINALLY!! Finding the NET PROFIT For Chocolate Cupcakes

Formula is: “NET PROFIT = TOTAL SALES – TOTAL EXPENSES”

NET PROFIT ($22.30) = TOTAL SALES ($76.50) – TOTAL EXPENSES ($54.20)

***YOU NEED TO FIND NET PROFIT FOR EACH RECIPE***

Please do comment here if you still in doubt… Your comments are very much appreciated!!

Reflection on Homework for Week 7 March 26, 2012

Filed under: Homework — computer_resources @ 4:51 am

Dear students,

Sorry for late marking of your homework!  I have tonnes of work to be done at UBD; my assignments, group working activities, meetings…. pheewww!! at last your homework completely checked~

So please have a check… I have came across that some of you haven’t submit your work.  They are Khairurrabi’ee, Hazwan, and Joane.

Here is a good example that I would like to acknowledge Muhd  Faris Syarifuddin bin Hj Hirwan.  He organised his table well by formating it with borders and colours.  Very neat, indeed!!  (*** DOUBLE CLICK ON THE IMAGE TO GET A FULL IMAGE)

Answer for Group 2: Revision on 27 Feb 2012

Filed under: Revision,Uncategorized — computer_resources @ 6:23 am

The spreadsheet below shows the results of student progress assessment (SPA) of core subjects for some year 8 students in a school.

a)     Write down a cell address which contains

i.   a label: A1 (other answers: B1, C1, D1, E1, F1, G1, H1, A2, A3, A4, A5. A6, A7)

ii.   a date: B2 (other answers: B3, B4, B5, B6, B7)

 

b)     What is the formula/function used to calculate the following:

i.  Total in G2: =SUM(C2:F2)

other answer: =C2+D2+E2+F2

ii.  Average in H2: =AVERAGE(C2:F2)

other answer: =(C2+D2+E2+F2)/4

 

c)     The display in cell H2 appears as “######’

i. What does this mean?

The cell is not wide enough to display its item.

ii.   How would you overcome this problem?

By widening the column so that the item can be displayed properly.

 

d)     Describe how you would copy the formula from G2 to G3:G7.

1.  Select cell G2, right-click on the mouse and select ‘Copy’.

2. Highlight cell G3:G7, right-click on the mouse and select ‘Paste’.

 

e)     List two of a function in a spreadsheet. (I’ve made change from formula to function)

1. =SUM(C2:G2)

2. =AVERAGE(c2:G2)

*The range can be anything.
