Problem 3:
Mary is having a birthday party. She invited 14 friends. Mary made 190 cookies. She wants to share them at her party but also wants to save 22 for her mother and father. How many cookies will each person get at the party?
####
Step-by-step Solution:
- Total cookies made:
190
- Cookies saved for parents:
22
- Cookies for the party:
$ 190 - 22 = 168 $
- People at the party: Mary + 14 friends =
15 people
- Cookies per person:
$ 168 ÷ 15 = 11.2 $
But since we're dealing with whole cookies, we need to interpret this carefully.
$ 168 ÷ 15 = 11 $ with a remainder of
3 (because $ 15 × 11 = 165 $, and $ 168 - 165 = 3 $)
So, each person gets
11 cookies, and there are
3 leftover cookies.
✔ Answer: Each person gets
11 cookies (with 3 left over).
