Christie (C) bakes 24 cookies per cookie sheet (s), if she already has 72 cookies baked:

a) create an equation to represent the situation.​ ​

b) How many more baking sheets would she need to bake 192 cookies? ​

• a) C = 24s + 72

  b) 5

• a) C = 72s + 24

  b) -3

• a) 72 - 24s = C

  b) 8

• a) s = 24C - 72

  b) 12
