Arne sells furniture. He is paid a salary by his store if $800 a month plus a commission on all sales. Last month his sales were 20,000 and he earned a total salary and commission of $1,200. How much commission was he paid? What rate (%) of commission was he paid?

He was paid $400 commission

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%
