Final answer:
Joel should use the inequality C. 0.03s + 42,500 > 65,000 to calculate the minimum sales required at OmegaCo to earn more than what he would at AlphaCo with a fixed salary. The correct answer is option C.
Step-by-step explanation:
To determine what his sales, s, need to be in order for Joel to earn a greater salary at OmegaCo than he would at AlphaCo, Joel should set up an inequality that compares the total potential earnings from both companies. AlphaCo offers a fixed salary, while OmegaCo offers a base salary plus a percentage of the sales made.
Thus, the inequality must represent the scenario where OmegaCo's pay structure results in a higher total salary than AlphaCo's fixed salary.
The correct inequality is OmegaCo's salary must be greater than AlphaCo's salary:
C. 0.03s + 42,500 > 65,000
This inequality can be solved to find the minimum amount of sales, s, Joel needs to make at OmegaCo to earn more than the fixed salary at AlphaCo.
