C)

$410

Step-by-step explanation:

We are given that Kelly’s paycheck varies directly with the number of hours she works.

We know that she received $133.25 for 13 hours of work.

Part A)

The standard form for the direct variation equation is:

Where k is the constant of variation.

Here, y is the paycheck amount and x is the number of hours Kelly worked.

We know that Kelly received $133.25 for 13 hours of work. Hence, y = 133.25 when x = 13:

Solve for k:

Therefore, our constant of variation is 10.25.

We can substitute this into our equation:

Therefore, our direct variation equation is:

Contextually, the equation tells us that Kelly earns $10.25 per hour.

Part B)

Using the equation, we can determine the the number of hours Kelly worked to earn $246. We can substitute 246 for y:

Solve for x:

Therefore, x = 24.

Therefore, Kelly must’ve worked 24 hours for her paycheck to be $246.

Part C)

We can use our equation. This time, we will substitute 40 for x and evaluate. Hence:

So, Kelly will earn $410 for working 40 hours.
