Final answer:
To calculate Danielle's net pay for the week, add her base salary to her commission on sales.
Step-by-step explanation:
In order to calculate Danielle's net pay for the week, we need to add her base salary and her commission. First, we calculate the commission by multiplying her sales amount ($895) by the commission rate (9% = 0.09). This gives us a commission of $895 * 0.09 = $80.55. Next, we add the base salary and the commission together to find her net pay: $450 + $80.55 = $530.55.
Therefore, Danielle's net pay for that week is $530.55, which is option b) $523.55.
