Major Assignment 1

Monthly budget, income analysis and conversion

Monthly Budget

Let’s get started.

1. Don’t forget to enter your name in Question 1.

2. Remember to enter the formulas in yellow cells, e.g., =(Number of)*(Cost per) in Total cost.

3. Don’t forget the subtotals, e.g., =SUM(“Total cost”).

Monthly Budget

1. For the bar chart, highlight both Budget Category and Subtotal.

2. Click “Insert” and choose the icon circled in red. That will automatically create a bar chart.

For the pie chart, the process is similar. When you highlight the second column (% of total), press Ctrl and click. That will select the second column. Then choose a pie directly below the red circle.

Income Analysis

1. In slope and Y-intercept, you need to find the slope and the y-intercept respectively.

2. Slope is explained here: https://support.microsoft.com/en-us/office/slope-function-11fb8f97-3117-4813-98aa-61d7e01276b9

3. Intercept is explained here: https://support.microsoft.com/en-us/office/intercept-function-2a9b74e2-9d47-4772-b663-3bca70bf63ef

4. Notice the order of variables inside the parenthesis.

Income Analysis (Scatterplot)

1. Highlight the cells.

Choose “Insert” and select the icon circled in red.

Income Analysis (Scatterplot)

1. Once the scatterplot shows up, choose “Add Chart Element.”

Choose “Trendline” and “Linear.”

Income Analysis (Scatterplot)

Right-click the trend line and choose “Format trendline.”

Next, choose the appropriate amount for “Forward” and “Backward.”

Conversions

Make sure to look for appropriate factors from the table above.

In yellow cells, you need to enter formulas (e.g., I entered =1/F10 in the red circle and 0.030 appeared).

In blue cells, you need to enter units.

Conversions (Temperature)

Make sure to enter the formulas (Do not use your calculator).

For the red circle, use = (5/9)*(F - 32).

For the blue circle, use = (9/5)*C + 32.
