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.

We have a triangle:
the side opposite the angle Ф is 4/5,
The side adjacent the angle Ф is 3/5
1) we calculate the hypotenuse, by the Pythagoras Theorem:
h=√[(4/5)²+(3/5)²]=1
2) we calculate the csc of Ф
csc Ф= hypotenuse / opposite side
csc Ф=1/ (4/5)=5/4
Answer: e. 5/4
