He is paid  2% commission on all of his sales

Step-by-step explanation:

He makes a flat rate of $800

He was paid $1,200, so he made $400 commission on $20,000  

($1,200 - $800 = $400)

Divide $400 by $20,000 to determine his commission rate...

$400/$20,000 = 0.02  

0.02 is 2%

Through out all the sale he was paid 2% of his commission, witch is $400
