He marked down dvd players by 36%, and he marked down stereo tuners by 22%. If dvd players cost $41. 60 after the markdown and stereo tuners cost $69. 42 after the markdown, which item’s price was reduced by more, and by how many dollars more was it reduced? round all dollar values to the nearest cent. A. The dvd player’s price was reduced by $3. 82 more than the stereo tuner’s price. B. The dvd player’s price was reduced by $27. 82 more than the stereo tuner’s price. C. The stereo tuner’s price was reduced by $0. 29 more than the dvd player’s price. D. The stereo tuner’s price was reduced by $27. 53 more than the dvd player’s price.
The dvd player’s price was reduced by $3. 82 more than the stereo tuner’s price.
Let the cost price of dvd players be D.Let the cost price of stereo tuners be S.Given the following data:
Markdown for dvd player = 36%Markdown for stereo tuner = 22%Markdown cost for dvd player = $41.60Markdown cost for stereo tuner = $69.42To determine which item’s price was reduced by more, and by how many dollars:
First of all, we would calculate the cost price of each item.
For dvd players:
Note: You'll pay 64% since it was markdown by 36%.
[tex]\frac{64}{100} \times D = 41.60\\\\64D=41.60 \times 100\\\\64D=4160\\\\D=\frac{4160}{64}[/tex]
D = $65
Reduction: Dvd player = [tex]65-41. 60=[/tex] $23.40
For stereo tuners:
Note: You'll pay 78% since it was markdown by 22%.
[tex]\frac{78}{100} \times S = 69.42\\\\78S=69.42 \times 100\\\\78S=6942\\\\S=\frac{6942}{78}[/tex]
D = $89
Reduction: Stereo tuner = [tex]89-69. 42=[/tex] $19.58
Now, we can calculate the difference in reduction of the cost price of both items:
[tex]Difference = 23.4 -19.58[/tex]
Difference = $3.82
Therefore, the price of the dvd players was reduced by $3. 82 more than the price of the stereo tuners.

Who played cleopatra in the caesars sportsbook commercial.
A student is bouncing on a trampoline. At her highest point, her feet are 95 cm above the trampoline. When she lands, the trampoline sags 25 cm before propelling her back up.
The time she spent in contact with the trampoline is 0.1619 seconds.
The objective of this question is to determine for how long she is in contact with the trampoline?
The conservational force is exerted on the trampoline is equivalent to the sum of the potential energy at the highest point and the elastic energy at the lowest point.
∴
From the given information;
[tex]\mathbf{mg \dfrac{(95 +25)}{100} = \dfrac{1}{2}k ( \dfrac{25}{100})^2}[/tex]
[tex]\mathbf{m\times g\times 1.2 = k(0.03125)}[/tex]
[tex]\mathbf{m\times 9.8 \times 1.2 = k(0.03125)}[/tex]
[tex]\mathbf{\dfrac{m}{k} = \dfrac{(0.03125)}{9.8 \times 1.2}}[/tex]
[tex]\mathbf{\dfrac{m}{k} = 0.002657}[/tex]
