Dean is a certified personal trainer, and before taking on new clients, he wants to finalize his pricing plans. One plan is to charge $10 for the initial consultation and then $45 per session. Another plan is to charge $30 for the consultation and $35 per session.

Answers

Answer 1

Answer: let a be the cost of the fist plan
b is the cost of the second plan
t is the number of session

a = 45t + 10
b = 35t + 30

solve when will the cost be equal
45t + 10 = 35t + 30
10t = 20
t = 2
after two session plan a will always be more expensive than plan b
