Answer:
f(x) = 2.30x + 22
Step-by-step explanation:
The company charges a connection fee each month for $ 22. And an additional $ 2.30 per cubic foot of water used. The price of the additional charge is dependent on the cubic foot of water used.
The total monthly charge can be computed as follows :
x = cubic feet of water used
Monthly connection charge = $22
The additional charge is dependent on the cubic feet of water used.
The additional charge is $2.30 per cubic foot of water used so it is $2.30 multiply by cubic feet of water used = 2.30x
Adding the monthly connection charge and the additional charge per cubic foot of water used you get the total monthly charge.
The total monthly charges function can be represented as
f(x) = 2.30x + 22
