Algebra Word Problems (Cookies)
Mary had a number of cookies. After eating one, she gave half the remaining to her sister. After eating another cookie, she gave half of what was left to her brother. Mary now has only five cookies left. How many cookies did she start with?
Let the initial number of cookies be x. After eating one, cookies left = x - 1. She gave half to her sister, so remaining = (x - 1)/2. She then ate another cookie, remaining = (x - 1)/2 - 1. She gave half of this to her brother, so remaining = ((x - 1)/2 - 1)/2 = (x - 1)/4 - 0.5. This equals 5 cookies, so (x - 1)/4 - 0.5 = 5. Solving: (x - 1)/4 = 5.5 => x - 1 = 22 => x = 23.
