Answer 2

Answer:

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

Step-by-step 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!
