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%

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

Step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
