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
Answer:
The slope is 3/8!
Explanation:
You put your equation in slope-intercept form, that is how you find the slope.
3x-8y=-20
-8y=-3x-20
y=3/8x-20
the fraction is now positive because the numerator and the denominator are both negative so they are changed into positive.

Answer:
the width of yuns area model is either 7x or (x - 2).
Step-by-step explanation:
Since yun is trying to factor 7x² - 14x and the greatest factor is 7x.
Thus,he will get;
7x(x - 2)
Now,since he made an area model. The area of a rectangular model is:
Area = Length x Width.
Now, let's compare this area with the factorization of yun.
We'll see that;
The length is either 7x or (x - 2)
Similarly, the width is either 7x or (x - 2).
Thus, the width of yuns area model is either 7x or (x - 2).
