At the local bakery, ariel bought 2 oatmeal cookies for $1.50. mei bought 1/2 dozen oatmeal cookies for $4.50. becky bought 8 oatmeal cookies for $6.00 use a graph to represent the situation? do the number of cookies and the cost have a proportional relationship?

1) in first place you must establish a table with a relation # cookies vs price

# cookies  2              6          8

      $         $1,5     $4,5  $6

with this table you obtain the proportion if divide 2/ 1,5 = 1,33333333

6/4,5 = 1,33333333 andd so on

the graph is for  y = x/ 1,33333333

2) for the last question it is affirmative, the cost and the cookies have a proportional relationship
