Answer:
The answer is 7.5.
Step-by-step explanation:
Since we're looking for half of 15, divide 15 by 2 (or multiply 15 by 0.5, it's the same thing) and you get 7.5.
I hope this helped! :)
The solution to given system of equations are ![(x , y) = ( \frac{-16}{5},\frac{-21}{20})](https://tex.z-dn.net/?f=%28x%20%2C%20y%29%20%3D%20%28%20%5Cfrac%7B-16%7D%7B5%7D%2C%5Cfrac%7B-21%7D%7B20%7D%29)
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
6x - 4y = -15 ----- eqn 1
x - 4y = 1 -------- eqn 2
We can solve the system of equations by susbtitution method
<em><u>From eqn 2, solve for varibale "x"</u></em>
x - 4y = 1
x = 1 + 4y ------- eqn 3
<em><u>Substitute eqn 3 in eqn 1</u></em>
6(1 + 4y) - 4y = -15
6 + 24y - 4y = -15
Combine the like terms
6 + 20y = -15
20y = -15 - 6
20y = -21
![y = \frac{-21}{20}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B-21%7D%7B20%7D)
<em><u>Substitute the above value of "y" in eqn 3</u></em>
![x = 1 + 4(\frac{-21}{20})\\\\x = 1 + \frac{-21}{5}\\\\x = \frac{5-21}{5}\\\\x = \frac{-16}{5}](https://tex.z-dn.net/?f=x%20%3D%201%20%2B%204%28%5Cfrac%7B-21%7D%7B20%7D%29%5C%5C%5C%5Cx%20%3D%201%20%2B%20%5Cfrac%7B-21%7D%7B5%7D%5C%5C%5C%5Cx%20%3D%20%5Cfrac%7B5-21%7D%7B5%7D%5C%5C%5C%5Cx%20%3D%20%5Cfrac%7B-16%7D%7B5%7D)
Thus solution to given system of equations are ![(x , y) = ( \frac{-16}{5},\frac{-21}{20})](https://tex.z-dn.net/?f=%28x%20%2C%20y%29%20%3D%20%28%20%5Cfrac%7B-16%7D%7B5%7D%2C%5Cfrac%7B-21%7D%7B20%7D%29)

Answer:
$267.15
Step-by-step explanation:
The way my math teacher showed me to do it is take the price you paid and multiply it by 1.x (x being the amount of the discount).
In doing that, $205.50 multiplied by 1.30 is $267.15 and the original price of the jersey.
Hope this helps :)
