Exercise 6
You are required to create a spreadsheet to document and calculate costs in business over the period of a year on a monthly basis. Start by entering in the data below into a blank (Format the amounts as Euro)
|
January |
Wages |
2000.00 |
Services |

|
|
Total costs |
|
Using the AutoSum function total the costs in the appropriate cell
Select the cell containing January. Grab the 'fill handle' (dot on the bottom right of the cell) and drag it 11 cells to the right. It should generate the names of all the months of the year.
Generate numbers for wages, services and materials as follows:
Wages stay the same for each month of the year
Services increase by €50 each month
Materials increase by €100 each month
Now copy the formula for 'Total costs' to all the other months.
Save it again and close it.

The main methods of representations and processing of charts
In Excel you can represent numbers in a chart. A chart is a graphical representation of numbers. On the Insert tab, you can choose from a variety of chart types, including column, line, pie, bar, area, scatter and more. The basic procedure for creating a chart is the same no matter what type of chart you choose. As you change your data, your chart will automatically update.
You select a chart type by choosing an option from the Insert tab's Chart group. After you choose a chart type, such as column, line, or bar, you choose a chart sub-type. For example, after you choose Column Chart, you can choose to have your chart represented as a two-dimensional chart, a three-dimensional chart, a cylinder chart, a cone chart, or a pyramid chart. There are further sub-types within each of these categories. As you roll your mouse pointer over each option, Excel supplies a brief description of each chart sub-type
