I know this sounds kinda selfish, but at 15, I have a business waiting to be set up. My sister, older than me, wants to model the clothing for $5-10 a piece. This is understandable as I would want to be paid too but what she doesn’t get it if I price something at $40, the company takes away 10-15% leaving me around $30- not the mention the $10-15 I spent on the item in the first place. So basically , I’d be making a $10-$15 profit and well, for a business that’s been built with no aid whatsoever, I don’t like this. What should I tell her?
