Answers

Answer

Find out the what is the salesman's commission as a percent of his total monthly sales.

To prove

Formula

$Percentage = (Part\ value*100)/(Total\ value)$

As given

A furniture store salesman had $15,200 in total monthly sales last month.

He made $912 in commission from those sales.

Here

Part value = $912

Total value = $15,200

put in the formula

$Percentage = (912* 100)/(15200)$

solve the above equation

$Percentage = (91200)/(15200)$

Percenatge = 6 %

Therefore the salesman's commission is 6% of his total monthly sales .

We need to find out what percentage $912 is of $15 200. The answer is 6%, if I'm understanding the question correctly.
