Student Cookies

Cook E. Doe School had a bake sale. At the sale, a package of 36 cookies cost $12.

Four students decided to put their money together and buy one package. Kayden

contributed $2, Kayah contributed $3, Kayla contributed $4, and Michelle

contributed $3. Everyone wants to be fair when dividing up the package.

How many cookies should each person get based on how much each paid?

Answer: The correct answer is Kayden - 6 cookies; Kayah-9 cookies; Michelle-9 cookies and Kayla - 12 cookies

Step-by-step explanation: There are 36 cookies. Kayden gives $2 - or pays for 1/6 of the cookies (2/12 = 1/6) The decimal for 1/6 is 0.16, so 36 x 0.16 = 5.88 rounded up to 6 cookies. Kayah contributed $ 3 - or pays for 1/4 of the cookies. (3/12 = 1/4) The decimal for 1/4 is 0.25, so 36 x 0.25 = 9, so Kayah and Michelle each get 9 cookies. Kayla gives $4 - or pays for 1/3 of the cookies (4/12 = 1/3) The decimal for 1/3 is 0.33, so 36 x 0.33 = 11.88 rounded to 12.

Step-by-step explanation:

Kayden:Kayah:Kayla:Michelle

2:3:4:3

2k+3k+4k+3k=36

12k=36

k=36:12

k = 3

Kayden - 2•3=6

Kayah - 3•3=9

Kayla = 4•3=12

Michelle = 3•3=9
