The system of equation that represents this situation is y = 20x + 15 for day and night kernel and y = 30x + 5 for bark time hotel.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Let y represent the total charges for for boarding a pet in x days.
Day and night kennel charges $20 per day plus a one-time food fee of $15 to board a pet. Hence:
y = 20x + 15
Bark time hotel charges $30 per day plus a one-time food fee of $5. Hence:
y = 30x + 5
The system of equation that represents this situation is y = 20x + 15 for day and night kernel and y = 30x + 5 for bark time hotel.

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.
<u>Given the following data:</u>
- Markdown for dvd player = 36%
- Markdown for stereo tuner = 22%
- Markdown cost for dvd player = $41.60
- Markdown cost for stereo tuner = $69.42
To 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.
<u>For </u><u>dvd players</u><u>:</u>
<u>Note:</u> You'll pay 64% since it was markdown by 36%.
![\frac{64}{100} \times D = 41.60\\\\64D=41.60 \times 100\\\\64D=4160\\\\D=\frac{4160}{64}](https://tex.z-dn.net/?f=%5Cfrac%7B64%7D%7B100%7D%20%5Ctimes%20D%20%3D%2041.60%5C%5C%5C%5C64D%3D41.60%20%5Ctimes%20100%5C%5C%5C%5C64D%3D4160%5C%5C%5C%5CD%3D%5Cfrac%7B4160%7D%7B64%7D)
D = $65
Reduction: Dvd player =
$23.40
<u>For </u><u>stereo tuners</u><u>:</u>
<u>Note:</u> You'll pay 78% since it was markdown by 22%.
![\frac{78}{100} \times S = 69.42\\\\78S=69.42 \times 100\\\\78S=6942\\\\S=\frac{6942}{78}](https://tex.z-dn.net/?f=%5Cfrac%7B78%7D%7B100%7D%20%5Ctimes%20S%20%3D%2069.42%5C%5C%5C%5C78S%3D69.42%20%5Ctimes%20100%5C%5C%5C%5C78S%3D6942%5C%5C%5C%5CS%3D%5Cfrac%7B6942%7D%7B78%7D)
D = $89
Reduction: Stereo tuner =
$19.58
Now, we can calculate the difference in reduction of the cost price of both items:
![Difference = 23.4 -19.58](https://tex.z-dn.net/?f=Difference%20%3D%2023.4%20-19.58)
Difference = $3.82
Therefore, the price of the dvd players was reduced by $3. 82 more than the price of the stereo tuners.

Answer:
the barosphere is made up of the parts of Earth where life exist over a long period of time the outer sphere develops a mix of oxygen
<span>They do not conduct heat very well because the particles are not as close together as in a solid and transference of heat by conduction occurs due to the vibrations of particles colliding and passing on their vibrations. More simply it is because atoms are less densely packed in liquids and gases. </span>
