Lesechka [4]
First we see the cost of making 200 cookies:
 (200) * (1.50) = 300 $
 Then, we see the amount of cookies that are not broken:
 (200) * (0.30) = 60
 200-60 = 140
 Arley wants to 50% markup on cost and produces 200 cookies:
 (300) * (1.50) = 450 $
 Arley can sell the broken cookies for $ 1.40 each:
 (1.40) * (60) = $ 84
 For each unbroken cookie the price will be then:
 (450-84) / (140) = 2.61 $
 Answer:
 Arley should charge $ 2.61 for each unbroken cookie
