Answer:
y = 140, x = 159
Step-by-step explanation:
Angle y:
we can find this angle by subtracting 40 from 180, 180-40 = 140 = y
Angle x:
Some measure of an angle plus angle b is equal to 180 degrees: 180-61 = 119
We can now find the measure of the third angle of the triangle: 180-(119+40) = 21
The third angle plus angle x is equal to 180: 180-21 = 159 = x

Answer 
Find out the total monthly charges for x cubic feet of water used .
To prove
As given
A water company charges a connection fee each month of $22 and an additional $2.30 per cubic foot of water used.
Than the equation become
Total monthly  charges for x cubic feet of water used = Monthly connection fee + charges for x cubic feet of water
thus
f(x) = 22  + 2.30x
where x is the  x cubic feet of water used .
Therefore Option (B) is correct i.e f(x) = 22  + 2.30x .
