Jeffrey is a kickboxing instructor who will be teaching classes at a local gym. To get certified
tatyana61 [14]

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

3x=200-50\\3x=150

Dividing both sides by 3

\frac{3x}{3}=\frac{150}{3}\\x=50

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