Answer:
operating profit = $0.445
Explanation:
given data
markup = 35% of cost
book price = $8.91
Overhead expense = 25% of cost
sale = 5% off regular price
solution
first we get here cost of the book (C) that is express as
Selling price = cost of book + markup
$8.91 = C + $0.35 C
cost of book = $6.6
and we know 5% discount at the marked price and 25 % overhead expenses so here operating profit will be
operating profit = book price × ( markup % - Overhead expense% - discount % )
operating profit = $8.91 × (35% - 25% - 5% )
operating profit = $0.445
