Question

Irene earned a commission of $5130 on sales of $90,000. What rate of commission was she paid? (Be sure to include the % symbol in your answer.)

Answer 1

We will have that $90000 is the total of sales and therefore the 100%, then we want to know the percentage that $5130 represents:

$p=\frac{5130\cdot100}{90000}\Rightarrow p=5.7$

She's getting a commission at a rate of 5.7%.
