1 answer

To calculate Nadia's commission for last week and for the year 2011, we can follow these steps:

Part 1: Last week's commission

Nadia earns a 12% commission on the stocks she sold.

Last week's sales amount: $7,500

Commission calculation: \[ \text{Commission} = \text{Sales} \times \text{Commission Rate} \] \[ \text{Commission} = 7500 \times 0.12 \] \[ \text{Commission} = 7500 \times 0.12 = 900 \]

So, last week Nadia made $900 in commission.

Part 2: Commission for 2011

To find out how much she made in commission for the entire year of 2011, we will assume she earned the same commission every week and there are 52 weeks in a year.

Annual commission calculation: \[ \text{Annual Commission} = \text{Weekly Commission} \times \text{Number of Weeks} \] \[ \text{Annual Commission} = 900 \times 52 \] \[ \text{Annual Commission} = 46800 \]

Thus, in 2011, Nadia made $46,800 in commission.

Final Answers:

  • Part 1: Last week, she made $900 in commission.
  • Part 2: In 2011, she made $46,800 in commission.
