If Jeffrey takes 50 classes in his first month as an instructor, he will earn back the amount he spent on certification.
Step-by-step explanation:
Amount spent on certification = $200
Base salary = $50
Payment per class = $3
Let, x be the number of classes.
J(x) = 50+3x
He needs to earn $200 dollars in first month, therefore,
50+3x=200

Dividing both sides by 3

If Jeffrey takes 50 classes in his first month as an instructor, he will earn back the amount he spent on certification.
