Question

The equation y=6.88x-199 models the number of visitors at a pool,y, and the air temperature in degrees there are 426 visitors at the pool one hot day what is the expected air temperature on that da round your answer to the nearest degree

Answer 1

`\approx 91^\circ`

Explanation:

The given equation to represent the model for the relationship between
`x` and
`y`.

`y=6.88x-199`

`x` represents the air temperature in degrees and

`y` represents the number of visitors at a pool.

Also given that number of visitors at the pool on a particular day is 426.

To find:

The expected air temperature as per the number of visitors.

Solution:

Here, we are given a linear equation to represent the relation between two variables.

Value of one variable is given and we have to find the value of other variable.

i.e. we are given that:

`y=426` and we have to find the value of
`x`.

Let us put the value in the equation:

`426=6.88x-199\\\Rightarrow 6.88x = 426 + 199\\\Rightarrow x = (625)/(6.88)\\\Rightarrow \bold{x \approx 91^\circ}`
