**Answer:**

Option B.

**Step-by-step explanation:**

It is given that AE and DF are parallel lines. Line GH intersect both lines. Line AE intersects with line GH at point B, line DF intersects with line GH at point C. As shown in the below figure.

m∠ABG = 11x and m∠HCF = 10x + 9.

From the below figure it is clear that ∠ABG and ∠HCF are alternate exterior angles. So, measure of these angles are equal.

The value of x is 9.

**Therefore, the correct option is B.**

Total cost of books was 15 + 10 or 25. With the 50 % discount on the $10 book, the total is now $20. The total cost was reduced by (B) 20%.

$5 off the $25 price is a 20% discount.
