Answer:
Step-by-step explanation:
Total copies of books ordered by Lena for his book club members is 12. The cost of the book is $19 each. Since the books are the same, the total cost of the books will be
19 × 12 = $228
the order has a $15 shipping charge. It means that the total amount that Lena would pay for the 12 books is total cost of the books + shipping fee. it becomes
228 + 15 =
=$243
