Answer:
B. 12.8
Step-by-step explanation:
I took the test.
Hope you pass( please mark(me) as brainiest.)
14 because - 11-17=-28. If you divide -28 by -2x you get 14
Original price of the item = $14.95
Price after discount = $13.79
Discount offered = original price - price after discount = 14.95- 13.79 = $1.16
Now let us find the percentage of discount offered.
Percentage discount is given by the formula:

Where MP= Marked price= original price
SP= selling price= price after discount

Percentage discount = 7.759 %
The answer is 3x.
Factor out 3x and u get 3x(x-3).
