Lucky customers randomly get a bonus brownie with their purchase according to the following probabilities: 10% of chocolate chip cookies come with a bonus brownie, and 25% of snickerdoodles come with a bonus brownie. If the bakery sells four times as many chocolate chip cookies as they sell snickerdoodle cookies, what is the percent likelihood that a sale chosen at random came with a bonus brownie?
