Answer:
The discount was A) $ 24.51 and B) 14.5% of the value.
Step-by-step explanation:
Since a department store offered a 10% discount on all humidifiers, and they also stated that the first 50 customers would receive an additional 5% discount off the sale price, if I purchase a humidifier that sells for $ 169 and I are among the first 50 customers, to determine what will my total discount be (a) in dollar amount and (b) in percent, the following calculation must be performed:
100 - 10 = 90
100 - 5 = 95
(169 x 0.9) x 0.95 = X
152.1 x 0.95 = X
144.49 = X
169 = 100
144.49 = X
144.49 x 100/169 = X
85.5 = X
Therefore, the discount was A) $ 24.51 and B) 14.5% of the value.
I think its 200%

V= a^3
So in this case V= 6^3
V= 216
To solve for the surface area of the pyramid, we make use
of the formula:
A= l w + l [sqrt ((w / 2)^2 + h^2)] + w [sqrt ((l / 2)^2 + h^2))
where,
l and w are the base of the pyramid = 100 mm
h is the height of the pyramid = 75 mm
Substituting the given values into the equation:
A= 100 * 100 + 100 [sqrt ((100 / 2)^2 + 75^2)] + 100 [sqrt ((100
/ 2)^2 + 75^2))
A = 10,000 + 100 (sqrt 2575) + 100 (sqrt 2575)
A = 20,148.90 mm^2
Therefore the surface area of the pyramid is about 20,149
mm^2.
