1. **Stating the problem:** Calculate the total salary if the base salary is 334 and there is an additional 13 for every item sold beyond 100. 2. **Formula used:** Total salary = Base salary + (Number of items sold beyond 100) \times Additional pay per item 3. **Explanation:** - The base salary is fixed at 334. - For every item sold beyond 100, an extra 13 is added. - Let $x$ be the total number of items sold. - The number of items beyond 100 is $x - 100$ (only if $x > 100$). 4. **Expression for total salary:** $$\text{Total salary} = 334 + 13 \times (x - 100)$$ 5. **Example:** If $x = 120$ items sold, $$\text{Total salary} = 334 + 13 \times (120 - 100) = 334 + 13 \times 20 = 334 + 260 = 594$$ 6. **Summary:** The total salary depends on the number of items sold beyond 100 using the formula above.
