An antique dealer visited three shops. She spent $25 at the first shop. At the second shop, she spent half of her remaining money. At the third shop, she spent one third of her remaining money and had $60 left. How much money did the dealer have originally?

started with x
(x  25) after first shop
(x25)/2 after second shop
(2/3)(x25)/2 after third shop
so
(2/6)(x25) = 60
