Question

Adam calculates his annual salary ( base pay and commission), y, using the model y = 0.28x + 38,000, where x represent his total sales for the year. What does the slope mean in context? ( The increase in total sales per salary; The increase in salary per total sales)

Answer 1

In the context of the model \( y = 0.28x + 38,000 \), the slope is 0.28. This slope represents the change in Adam's salary for every one unit increase in total sales (x). Specifically, it indicates that for every additional dollar in total sales, Adam's salary increases by $0.28.

Thus, the correct interpretation of the slope in this context is **"The increase in salary per total sales."**
