Question

The water bill paid for the month (y) is related to the number of cubic meters of water
consumed (x) + other charges, represent the water bill.

Answer 1

Given:

Given that, the water bill paid for a month $(y)$ is related to the number of cubic meters of water consumed $(x)$ + other charges.

To find:

We need to represent the water bill.

Solution:

The water bill paid for a month $=y$.

According to the question, $y$ is related to the number of cubic meters of water consumed $(x)$ + other charges.

Let, $oc=$ other charges.

So, it can be represented as

$\Rightarrow y =x+oc$

Here, value of $y$ changes as $x$ value varies.

Hence, $x$ is independent variable and $y$ is dependent variable.

Consider a example:

Let $x=100$ cubic meters and other charges $=oc=\ 5$

So, the bill is $y=\ 100+\ 5=\ 105$

Therefore, the water bill is represented as $y =x+oc$.
