Answer:
C=100
Step-by-step explanation:
If a coat is regularly $125, and they mark it down to $75, we could figure out how much money was taken off by subtracting $75, from $125
$125 - $75 = $50
So the coats price was cut by $50.

Answer:
b
Step-by-step explanation:
B
Answer:
![y=2sin[\frac{\pi}{4}(x+3) ]-5](https://tex.z-dn.net/?f=y%3D2sin%5B%5Cfrac%7B%5Cpi%7D%7B4%7D%28x%2B3%29%20%5D-5)
Step-by-step explanation:
The standard form for a sinusoidal function is given by:
y = Asin[B(x - C)] + D
Where A is the amplitude of the sine wave, the period is 2π/B, C is the phase shift and D is the vertical displacement / translation
Given:
A = 2, D = -5 (down), C = -3 (left).
8 = 2π/B; B = π/4
Therefore:
![y=2sin[\frac{\pi}{4}(x+3) ]-5](https://tex.z-dn.net/?f=y%3D2sin%5B%5Cfrac%7B%5Cpi%7D%7B4%7D%28x%2B3%29%20%5D-5)
