Time to Win Some Money!

CONGRATULATIONS! You have WON!!!  You have won \$1,000,0000  How would you like to spend it?  You may spend it on ANYTHING you want.  But as always, there are a few conditions.

The fine print  You must spend one million dollars to the exact cent.  You cannot buy more than one of any item. E.G. You cannot buy two houses or two cars.  You must cut every item you purchased out from a catalogue, newspaper or internet with costs or receipts.  All ‘cut outs’ must have the price clearly marked.  All of you working out must be done in your workbook and show your understanding of trading.  Prices need to be added up on an Excel spreadsheet, that ends with the eventual balance of zero dollars.  You could purchase items at random or follow a common theme. Eg. Setting up a house or going on a holiday.

Step One: Create a budget. Item NumberItem DescriptionItem Cost Total Cost  This is a list of the items that you would like to buy and an estimation of their cost.  Don’t forget to work out the total cost of all of the items.

Step Two: Go Shopping!  This is the fun part!  Begin with the ‘big ticket’ items.  Make sure you cut out the item and that price is clearly marked.  You may use newspapers, magazines and catalogues. You may also use the internet at home.  Test your estimation skills  Complete your shopping before you do any of your working out.  See how close you can get to your \$1,000,000 budget.

Step Three: Calculating  You will need to keep track of your spending by subtracting the cost of each item as you go.  You must show your ability to subtract with borrowing. Hint…  You will be able to double check your work by completing the ‘inverse operation’. This means adding up the cost each item \$1,000,000 - \$2,995Swimming pool \$997,005Subtotal

Step Four: Keeping a Record  You will need to keep a record of your spending in your Maths book. When you have finished…  You mayn input all of your spending into Microsoft Excel  You will need to use the ‘Auto Sum’ function to add up the cost of all of your items.  Your teacher will be able to help you with this Item NumberItem DescriptionItem Cost Total Cost
