Awater company charges a connection fee each month of $22 and an additional $2.30 per cubic foot of water used. which function could be used to find the total monthly charges for x cubic feet of water used? a) f(x) = 2.30x b) f(x) = 2.30x + 22 c) f(x) = 22x + 2.30 d) f(x) = 2.30x − 22

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 .

angle addition postulate

2x=56
