Question

Erin's salary is determined by the number of hours she works, h, and the amount of sales, s, she makes. An expression that describes her salary is 8h + 12(h - 40) + 0.065, where h is greater than or equal to 40. Which part of this expression depends on the number of hours Erin works?

Answer 1

Erin's hourly wage and overtime pay depend on the number of hours she works, which are represented by the terms 8h and 12(h - 40), respectively, in the expression for her salary.

Step-by-step explanation:

The part of the expression that depends on the number of hours Erin works is 8h + 12(h - 40). Here, Erin's basic hourly wage is represented by 8h, which indicates she earns $8 for each hour she works. The second term, 12(h - 40), represents the additional wages she earns for hours worked beyond 40, often referred to as overtime pay. If Erin works more than 40 hours, she earns $12 for each hour overtime, which is common in many compensation structures. The third term, 0.065s (assuming it should be 0.065s as 's' represents the amount of sales), is a commission based on her sales and is not dependent on the hours she works.
