Will give brainliest she sells musical instruments and equipment at let it rock at the mall. she earns a commission of 5% on the first $6,000, 7 1/2% on the next $6,000, and 10% on sales over $12,000. her total sales for the month are $14,640. what is her total commission?explain every step

Hello!

Her first commision would have to be multiplied by 5% first, which would be 6,000 x .05

This would equal to $300.

The second part would be .075 x 6000.

This equals to $450

Then, .01 x 12,000

This equals to $120.

Add all commisions, 300+450+120

$870 is the total commision she received.

I hope I did this right. It's my first time on Tell me if you got it. Sorry if I didn't help

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
