Final answer:
The sales associate's goal for gross income should be $61,538 (option C).
Step-by-step explanation:
To calculate the sales associate's goal for gross income, we need to consider the expenses such as Social Security, Medicare, and operating expenses that average 35% of the gross income. Let's assume the sales associate's goal for gross income is 'G'.
So, the net income after deducting expenses would be 65% of G, which is equal to $40,000. This can be written as:
0.65G = $40,000
To find the value of G, we can divide both sides of the equation by 0.65:
G = $40,000 รท 0.65 = $61,538
