Question: Out of the 200 cookies that Javier baked from the recipe he learned online, his wife took 30%, and his daughter took 40 from the remaining cookies. If he ate half of the remaining cookies, how many cookies did they not eat?
Answer: From the 200 cookies, Javier's wife ate 30 / 100 * 200 = 60. After the wife ate 60 cookies, the number of cookies that remained was 200 - 60 = 140. The daughter also ate 40 cookies leaving 140 - 40 = 100 cookies. If Javier ate half of the remaining cookies, he ate 1 / 2 * 100 = 50. The number of cookies that remained is 100 - 50 = 50. The answer is 50.
