Scenario Mode

👤 Your Role: You are a sales analyst at a retail company.

📋 Request: Your manager wants you to prepare a report showing sales amounts rounded in different ways to help with pricing decisions.

📊 Data: You have a list of sales transactions with exact sales amounts including decimals.

🎯 Deliverable: Create a table showing the original sales amount, the amount rounded to the nearest whole number, rounded up to the nearest whole number, and rounded down to the nearest whole number.

Sample Data

Transaction ID	Sales Amount
1001	23.45
1002	19.99
1003	45.67
1004	12.01
1005	30.50
1006	27.89
1007	15.25
1008	40.75

Step 1: Add a new column next to Sales Amount named 'Rounded (Nearest Whole)'. Use the ROUND function to round each sales amount to the nearest whole number.

=ROUND(B2, 0)

Expected Result

For 23.45, the result is 23; for 19.99, 20; for 45.67, 46.

2

Step 2: Add another column named 'Rounded Up (Ceiling)'. Use the ROUNDUP function to always round each sales amount up to the nearest whole number.

=ROUNDUP(B2, 0)

Expected Result

For 23.45, the result is 24; for 19.99, 20; for 45.67, 46.

3

Step 3: Add a third column named 'Rounded Down (Floor)'. Use the ROUNDDOWN function to always round each sales amount down to the nearest whole number.

=ROUNDDOWN(B2, 0)

Expected Result

For 23.45, the result is 23; for 19.99, 19; for 45.67, 45.

4

Step 4: Copy the formulas down for all rows to apply rounding to all sales amounts.

Drag the fill handle from row 2 down to row 9 for all three rounding columns.

Expected Result

All sales amounts are rounded correctly in each new column.

Final Result

Transaction ID | Sales Amount | Rounded (Nearest Whole) | Rounded Up (Ceiling) | Rounded Down (Floor)

1003           | 45.67        | 46                      | 46                   | 45
1004           | 12.01        | 12                      | 13                   | 12
1005           | 30.50        | 31                      | 31                   | 30
1006           | 27.89        | 28                      | 28                   | 27
1007           | 15.25        | 15                      | 16                   | 15
1008           | 40.75        | 41                      | 41                   | 40
