I have no clue HOW to do this kind of problem, I don't want the answer, I just want an explanation.
Here is the question: Carla gets a base salary of $15,000 per year plus 5% commission on every house that she sells. If she sold $900,000 in homes last year, what was her final salary?
Thanks so much!

Multiply
0.05 * 900,000 = ______ commission
Add the commission to the base salary to find her total salary.
