Answer:
C = ![\frac{3L+120}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3L%2B120%7D%7B4%7D)
Step-by-step explanation:
Given
L =
(C - 30)
Multiply through by 3 to clear the fraction
3L = 4(C - 30) ← distribute
3L = 4C - 120 ( add 120 to both sides )
3L + 120 = 4C ( divide both sides by 4 )
= C
The domain is the X coordinates.
The bottom black dot is on X =-4 and the top black dot is on X = 6.
Because the dots are solid black, this means the X coordinate is part of the solution ( equal to).
This means the domain is greater than or equal to -4 and less than or equal to 6
which would be written as -4=< x<=6

Answer: 2000$
Step-by-step explanation: We start with the discounted price, which is 20% off. We let the original price equal x, x *( 1 - 20%) = 1600. x= (1600)/0.8 = 2000. Hope this helps.
