Baked Cookie Calculation

A small bakery sells three types of cookies: chocolate chip, oatmeal raisin, and peanut butter. The bakery sold a total of 120 cookies over a weekend. On Saturday, they sold three times as many chocolate chip cookies as peanut butter cookies. Additionally, they sold half as many oatmeal raisin cookies as peanut butter cookies. If the bakery sold 24 peanut butter cookies, how many chocolate chip cookies did they sell?
