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?

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.

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1

the answer is 11.2 (i know i’m late)
