Answer 2

If the student worked 21 hours this month, she will earn $246.75.

Explanation:

Let
`x` equal hours.

If the student earns $11.75 per hour, we can represent this with the expression:

`11.75x`

If she worked 21 hours this month, then:

`x=21`

With that information, we can substitute
`21` for
`x` in the initial expression:

`11.75(21)`

Multiply:

`246.75`

Therefore, if the student worked 21 hours this month, she will earn $246.75.

-

We can check our work by setting the initial expression equal to our solution:

`11.75x=246.75`

Divide both sides of the equation by the coefficient of
`x`, which is
`11.75`:

`x=21`

Since this quotient matches the number of hours she worked, our solution is correct!
