Answer:
d. total amount of commission earned
Step-by-step explanation:
A salesperson earns a weekly base salary plus a commission of 20% of all sales over the first $500.
This situation can be represented by the expression [tex]750+0.2(x-500)[/tex]
0.2(x-500) means total amount of commission earned.
This is because firstly its given that 20% is commission so we have 0.2.
The x-500 represents the sales over $500, where x is total sales. Like the person sold $800 worth of items so he will get 20% commission on $300.
