Questions and Answers

1.

Katie has a bag of 43 cookies. She and her 14 friends want cookies. Does Katie have enough so that everyone can have 3 cookies? Yes or No

Explanation
Since Katie has 43 cookies and there are 14 friends, the total number of people who want cookies is 14 + 1 (Katie) = 15. If each person wants 3 cookies, the total number of cookies needed would be 15 x 3 = 45. Since Katie only has 43 cookies, she does not have enough for everyone to have 3 cookies. Therefore, the answer is "No".
