Tanvi is a kickboxing instructor who will be teaching classes at a local gym. To get certified as an instructor, she spent a total of $80. Tanvi will be earning a base salary of $50 per month from the gym, plus an additional $15 for every class she teaches. If Tanvi teaches a certain number of classes during her first month as an instructor, she will earn back the amount she spent on certification. How much will Tanvi's expenses and earnings be?

Answer:

I think the answer is 4. if my math is correct
Y=Mx+b
Y being the amount she spent $80 m being the amount per class and b being base amount paid it’s
80=15x+50
Subtract 50 from the 80
30=15x
Divide 30 by 15 and
X=2 she has to teach 2 classes
