A sweater is marked down 15% off the original price. If the original price was $49.00, what is the sale price of the sweater before sales tax?

$41.65

Step-by-step explanation:

49.00 *15%=7.35

49.00-7.35= $41.65

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
