There are 78 cookies in box C, 26 cookies in box B and 10 cookies in box A.

let the number of cookies in first box be represented mathematically as B-16

the number of cookies in second box be represented as B

the number of cookies in third box be represented as 3B

Since there are 124 cookies we can make an equation such that it becomes

B-16 +B +3B =124

Solving for B, we have

5B -16 =124

5B =124 +16

5B =130

B=130/5

B=26

Therefore Box A contains B-16 =26-16 =10 cookies

Box C contains 3B =3 X 26=78 cookies

Answer: Equation (y = 3x + 10)

Each time the number of triangles increase, the 3 also increases. For example: 2 Triangles = 3 + 3 and the 2 of the 5 remains the same no matter how many triangles there are.

Step-by-step explanation:

Let x = Number of triangles

Let y = Perimeter

Plug in formula: y = 3x + 10

y = 3 (2) + 10

y = 6 + 10

y = 16
