Answer:
where k is the constant of proportionality
Step-by-step explanation:
Total amount earned by Cameron every hour = $7
Total amount varies directly with the number of hours she works.
Let the total amount earned by Cameron be represented by y.
Let the total number of hours worked by Cameron be represented by x.
Then y is directly proportional to 7*x.
Let k be the constant of proportionality.
=> ![\[y = k*7*x\]](https://tex.z-dn.net/?f=%5C%5By%20%3D%20k%2A7%2Ax%5C%5D)
=> ![\[y = 7kx\]](https://tex.z-dn.net/?f=%5C%5By%20%3D%207kx%5C%5D)
