Daniel collects Russian dolls that normally cost $4 each. He saves enough money to buy 15 Russian dolls. However, the price suddenly drops to $3 each. How many Russian dolls can he buy now at the discounted price, given his savings?

How much money has he saved? ** With the price of each doll at $4, this means he has saved a total of 15 * 4 = $<<15*4=60>>60.
How many dolls can he buy now at the discounted price? ** When the price is lowered to $3 each, he can now purchase 60 / 3 = <<60/3=20>>20 dolls.
