Answer:
The new price is 11.99
Step-by-step explanation:
First find the mark down
14.99 * 20 %
14.99 * .20
2.998
3.00
Subtract the markdown from the price
14.99-3.00
11.99
The new price is 11.99
Consider the polynomial identity (difference of squares):
(x+y)(x-y) = x² - y²
Set x =7 and y = 2 to obtain
(7+2)*(7-2) = 7² - 2²
9*5 = 49 - 4
45 = 49 - 4
This is the result required, obtained by using difference of squares.
Answer: Difference of squares.
