Maria has 19 cookies. She decided to give her friend 5 of them, and half of the rest to her family. From the rest, Maria decided to eat 2 cookies. How many cookies will she have left?
Thoughts? Step-by-step reasoning:
Maria wants to give away 5 cookies, so she will be left with 19 - 5 = 14 cookies. Half of these will go to her family, which means 14 / 2 = 7 cookies. Maria decided to eat 2 / 7 * 7 = 2 cookies. So she will be left with 7 - 2 = 5 cookies.
Thus, the answer is 5.
