Step-by-step explanation:
we can factor out z
so that'll be
z((1/m)-(1/n))=1

z=1/((1/m)-(1/n))
I can't tell if there's more the problem wants you to do. I could rewrite the equation on paper more easily, but I don't have one on hand
Wx+yz=bc
-yz. -yz
Wx=bc-yz
Wx/W=bc-yz/W
x=bc-yz/W
Answer:
I believe it would be five dollars since if you divide the price with the percentage yknow
