The domain of C = All positive real numbers
The given relationship is:
C = 20W
where:
W represents the weight of the letter in ounces
C represents the cost of sending the letter in cents
The domain of a function is a set of all the input values.
In the function C = 20W, the weights (W) represent the input values.
Since the weight of a letter cannot be negative, it can only contain positive real numbers (Both integers and decimals)
Therefore, the domain of C is a set of all positive real numbers

x = 32
Explanation : To answer this you want to get the x by itself. Subtract 4 from 20 which would make the equation 1/2x = 16. Next, divide 1/2 by 1/2x and 16. 1/2 and 1/2 cancel each other out and 1/2 divided by 16 is 32 hence x = 32.
