To calculate Nadia's commission for last week, you can use the following formula:

\[ \text{Commission} = \text{Sales} \times \text{Commission Rate} \]

Given that Nadia sold $7,200 worth of stocks and her commission rate is 11% (or 0.11 in decimal form):

\[ \text{Commission} = 7,200 \times 0.11 = 792 \]

So, Nadia made $792 in commission last week.


For part two, to calculate how much she made in commission for the entire year of 2011, we first need to determine how many weeks there are in a year.

There are 52 weeks in a year, so:

\[ \text{Annual Commission} = \text{Weekly Commission} \times 52 \] \[ \text{Annual Commission} = 792 \times 52 = 41,184 \]

Thus, if she averaged the same amount each week in 2011, she made $41,184 in commission for that year.

So the responses are:

  • Last week, she made $792 in commission.
  • In 2011, she made $41,184 in commission.
