A) Commission made last week is $ 288

B) Commissions earned in a year,treating a year as having exactly 52 weeks is $ 14976

Solution:

From given,

Commission rate = 4 %

Last week,she sold $7,200 worth of stocks

A. ) How much commission did she make last week?

Therefore,

$Commission\ amount = 4 \% of\ 7200\\\\Commission\ amount = 4 \% \times 7200\\\\Commission\ amount = \frac{4}{100} \times 7200\\\\Commission\ amount = 4 \times 72\\\\Commission\ amount = 288$

Thus commission made last week is $ 288

Given that,

If she were to average that same commission each week

To find the commissions earned in a year, treating a year as having exactly 52 weeks

Therefore,

$commissions\ earned\ in\ a\ year = 288 \times 52\\\\commissions\ earned\ in\ a\ year = 14976$

Thus commissions earned in a year,treating a year as having exactly 52 weeks is $ 14976
