The total cost without the discount is given by:
$
Then, to find the discounted amount, we make the following rule of three:
10 $ ------------------> 100%
x ----------------------> 20%
From here, we clear the value of x.
We have then:
![x = (\frac{20}{100}) * (10)\\x = 2](https://tex.z-dn.net/?f=%20x%20%3D%20%28%5Cfrac%7B20%7D%7B100%7D%29%20%2A%20%2810%29%5C%5Cx%20%3D%202%20%20%20)

A. The independent variable is time, as time is manipulating the value of her salary.
b. The dependent variable is her cost because what she charges for babysitting depends on how long she works.
c. y = 8x
y = how much she charges for this job
8 = the amount she charges per hour
x = number of hours babysat
Answer:
B
Step-by-step explanation:
Set up the equation
z = ![\frac{kx^2}{y}](https://tex.z-dn.net/?f=%5Cfrac%7Bkx%5E2%7D%7By%7D)
Plug in the numbers to find the value of k
3 = ![\frac{k(2^2)}{4}](https://tex.z-dn.net/?f=%5Cfrac%7Bk%282%5E2%29%7D%7B4%7D)
12 = 4k
3 = k
Solve to find the value of z
z = ![\frac{3(4^2)}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B3%284%5E2%29%7D%7B9%7D)
z = ![\frac{3(16)}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B3%2816%29%7D%7B9%7D)
z = 48/9
z = 16/3
