Step-by-step explanation:
Given:
Cost of price of cookie = $3 each
Number of cookies = 80
Damaged = 10%
Markup on cost = 60%
Find:
Cost of selling price
Computation:
Total cost of cookie = 80 × 3 = 240
Markup price = 240 + 240(60%)
Markup price = 384
Number of damage cookies = 80(10%) = 8
Remain cookies = 80 - 8 = 72
Cost of selling price = Markup price / Remain cookies
Cost of selling price = 384 / 72
Cost of selling price = $5.33 (Approx)
