Marcus earns 15% commission on his total sales at work.

IrinaVladis [17]

Answer:

Option C

Step-by-step explanation:

Given the following question:

Total cost is $725
15% Marcus makes in commission.

In order to find the answer, we have to find 15% of $725 and that number will be the total in commissions he earned that week.

$\frac{15\times725}{100} =15\times725=10875\div100=108.75$

Marcus makes "$108.75" or option C in commissions last week.

Hope this helps.
