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 .
Step-by-step explanation:
tan 60 = 21 ÷ y
1.73 = 21 ÷ y
y = 21 ÷ 1.73
y = 12.14
tan 30 = x÷ 12
0.6 x 12 = x
x = 7.2
