1. **State the problem:** We need to find the commission earned by an employee based on total revenue, sales, and cancellations. 2. **Given data:** - Total revenue per week = 390 - Sales per week = 20 - Average cancellations per day = 2 - Number of days per week = 5 3. **Calculate total cancellations per week:** $$\text{Total cancellations per week} = 2 \times 5 = 10$$ 4. **Calculate total number of sales per week:** $$\text{Total sales} = \text{Sales per week} - \text{Total cancellations per week} = 20 - 10 = 10$$ 5. **Calculate average sale value:** $$\text{Average sale value} = \frac{\text{Total revenue per week}}{\text{Total sales}} = \frac{390}{10} = 39$$ 6. **Determine commission rate based on average sale value:** - If average sale value is 0-40, commission = 0% - If average sale value is 41-100, commission = 5% - If average sale value is 101+, commission = 10% Since average sale value is 39, commission rate = 0%. 7. **Calculate commission earned:** $$\text{Commission} = \text{Total revenue per week} \times 0\% = 390 \times 0 = 0$$ **Final answer:** The commission earned is 0.
