Answer:the amount that the bookstore pay the publisher for the book is $64.4
Step-by-step explanation:
Let x represent the amount that the bookstore pay the publisher for the book.
The college bookstore marks up the price that it pays the publisher for a book by 35%. This means that the value of the mark up would be
35/100 × x = 0.35 × x = 0.35x
Therefore, the amount that the bookstore is selling the book would be
x + 0.35x = 1.35x
If the selling price of a book is $ 87.00, then it means that
1.35x = 87
x = 87/1.35 = 64.4
= 6x + 6x - 6x × 7 + 6xy - 7y
36x2 - 42x + 6xy - 7y
