1. Main Activity – Movie Premier Confectionary Budget Year 7 – Excel Tutorial (c) Corbett2011

2. Open the Movie Premier Confectionary Budget spreadsheet. Your boss has asked you to increase the budget allowed by £250. Amend the table to show the new budget. Increase budget here. (c) Corbett2011

3. You have recently changed suppliers. Notice in cell reference E7 that there is a supplier discount of 7%. This discount needs to be applied to all items. Insert two new columns between unit price and quantity purchased. Label the column Discount and the other Disc Price (as shown below). The formula in cell F7 has changed because a new column has been inserted. Previously the formula was in cell D7 and stated =SUM(D4:D8). It changed automatically . (c) Corbett2011

4. You will now calculate the value of the discount against the unit price in the discount column. In cell reference C4 input the formula =B4*G1. Cell reference C4 now holds the value of the calculation B4*G1. Both B4 and G1 are inputs and C4 is the output. Change the unit price of popcorn to £1.70. What happens to the value of the discount in cell C4? You now want to copy the formula in cell C4 down the column until you reach cell C8. Use the fill handle technique. What happened to the remaining cells in the column? Why do you think this happened? Continue on next slide... (c) Corbett2011

5. Absolute & relative cell reference When you copied the formula down the columns using the fill handle Excel assumed that the row numbers should increment (i.e. count up). Look at cells C5 and C6. This is because the cell reference used in the formulae is called a relative cell reference. A relative cell reference adjusts to its new location when it is copied. It is very clever and also very useful in most cases. An absolute cell reference does not change, even when it is copied it will always reference the same cell. Absolute references are not always used but they are useful when a specific cell needs to be referenced. The absolute reference is given by placing a dollar sign $ in front of the column letter, row number or both. (i.e. $G$1 means that the column and row will not change). (c) Corbett2011

6. In this activity, the supplier discount percentage is given in one cell only. Therefore, an absolute reference is required. Change the formula in cell reference C4 to B4*$G$1 Now copy the formula down the column to cell C8 using the fill handle. In column Disc Price you want to show the new unit price after the discount has been deducted. What operation do you think you will use for this column? In cell reference D4 input the formula =B4-C4 and use the fill handle to copy the formula down the column. It is okay to use a relative cell reference for this formula because we want the row number to increase. For hotdog row we only want to calculate the discount price for hotdogs so the formula should be =B7-C7. Check it now. (c) Corbett2011

7. You may have noticed that the values in Sub Total Spend column (F) has not changed throughout this activity so far. This is because the formulae references the Unit Price and the Quantity Purchased columns. The cell reference is relative and therefore updated when you inserted extra columns. You challenge is to amend the formula in column F to sum (i.e. add together) the Disc Price and Quantity Purchased columns. (c) Corbett2011
