Question

Bailey is making festive cookie bags. She tried to split all her cookies evenly by putting 15 per bag, but the last bag had only 14 cookies. So, she tried putting 10 cookies per bag, but the last bag had only 9. Her mom brought 2 more cookies. Now, Bailey tries 9, then 8, cookies per bag, but she can’t do it. Finally, Bailey puts 7 cookies in each bag evenly! What is the least possible total number of cookies?

Answer 1

Hi! The answer would be 21.

Explanation:

First, we must add.

`15 + 14 = 29`

29 is our first number. Bailey cannot evenly split the cookies into each bag with that amount of cookies, so we must move on to the next number.

`10 + 9 + 2 = 21`

21 can be divided 3 times by 7. Now we know the least amount of cookies total, is 21.

Hope this helped!
