Question says that "A salesperson earns $450 per week plus 15% of her weekly sales. "

So the expression representing her earnings is given by 450 + 0.15x.

Now we have to find the equation/inequality that describes the sales necessary for the salesperson to earn at least $600 in one week.

at least $600 means 600 or more

so that means earning (450+0.15x) is equal to 600 or more than 600

so required inequality will be:

450+0.15x≥600.

Hence correct choice for the final answer will be choice which matches with 450+0.15x≥600.
