<h3><em></em></h3><h2>Step-by-step explanation:</h2><h3></h3><h3>First you need to add her fixed weekly pay which can be expressed like this.</h3>
<em>150 x 4 = 600</em>
<h3>Then you need to calculate her commission, considering she has a 13% commission on all her sales, and she made 3740 dollars in sales her commission can be calculated like this.</h3>
<em>3740 x .13 = 486.2</em>
<h3>Finally the question asks how much money she made in total during the four weeks which can be shown by just adding the two numbers we got earlier.</h3>
