Answer 2

Answer: in my opinion, its 1/4 of the necklace price, because, if y=4x, then x= y/4, therefore the revenue(y) is 1/4 of the necklace cost( the price to build/make the necklace - the selling price, considering that she sells for a price higer than the fabrication price),

I don't think that this actually helped, but i hope i did, also, I'm not good at explanations nor sure that i get the problem rigth, good luck bro ;)
