Explanation: Here we are working with percentages. So when we have a 5.1% we can represent it as
[tex]\frac{5.1\%}{100\%}=0.051[/tex]Step 1: So once the sales representative has sold $66,770 we can calculate her commission as follows
[tex]66,770\cdot0.051=3405.27[/tex]Final answer: So her commission last month was $3405.27
