Explanation:
610 • 0.32 = 1,105.6
Then you’re going to add everything up:
650 + 260.40 + 260.40 + 16.95 + 11.56 + 10.56 + 17.84
And get =
1,227.73
And you’re going to subtract that with 1,105.6 and get the answer.
The answer to this equation is y=4
Answer:
The exact charge per cubic foot of water usage is 4 Cents.
Step-by-step explanation:
Let the per cubic foot charge be $ 'x' and the fixed charge be $ 'y'.
A household using 1100 cubic feet was billed $ 114.
Therefore, we get the equation,
.......( A )
And other household 1500 cubic feet was billed $ 130.
Therefore, we get the equation,
......( B ).
Now, we subtract equation A from equation B.
.....( B )
......( A )
