Question

Piper works at a camera store. He is paid an hourly rate plus 16% commission on everything he sells. One week, he was paid $515 for working 20 hours and selling $1,500 worth of camera equipment. What is his hourly rate?

Answer 1

His hourly rate is $13.75

Here, we want to get Piper's hourly pay at work

Let the hourly rate be h

Thus, for working 20 hours, the amount for this will be; 20 * h = 20h

Now, out of the $1500 sales, he is entitled to 16%

That means;

$\frac{16}{100}\times\text{ 1500 = 240}$

Thus, we have it that;

$\begin{gathered} 20h\text{ + 240 = 515} \\ 20h\text{ = 515-240} \\ 20h\text{ = 275} \\ h\text{ = }\frac{275}{20} \\ h\text{ = \ 13.75} \end{gathered}$
