An employee receives a weekly salary of
and a 6% commission on all sales.
Which rule best describe the function
that gives weekly earnings in terms of
dollars in sales

To calculate the weekly earnings of the employee, we need to add their fixed salary of $340 to the earnings from their sales commission. Since the employee earns a 6% commission, that would be represented as where is the total sales in dollars. So the function that describes the weekly earnings in terms of sales is . This means for every dollar in sales, the employee earns 6 cents in addition to their base salary.

When it comes to commissions, it’s easy to overlook the small details. A common mistake is to confuse percentages with decimal representations, which could lead to an incorrect function choice. Another frequent pitfall is forgetting to add the base salary; some might mistakenly think the commission is the only component. Always double-check that you are accounting for both earnings streams!
