Answer: For 10 sessions, the cost of the two plans the same.
Step-by-step explanation:
Let x= Number of sessions.
Given: Christian’s Gym charges a one-time fee of $50 plus $30 per session for a personal trainer.
Total charge for x sessions = 50+30x
Nicole's fitness center charges a yearly fee of $250 plus $10 for each session with a trainer.
Total charge for x sessions = 250+10x
When both plan charges the same, then
![50+30x=250+10x\\\\\Rightarrow\ 30x-10x=250-50\\\\\Rightarrow\ 20x=200\\\\\Rightarrow\ x=10](https://tex.z-dn.net/?f=50%2B30x%3D250%2B10x%5C%5C%5C%5C%5CRightarrow%5C%2030x-10x%3D250-50%5C%5C%5C%5C%5CRightarrow%5C%2020x%3D200%5C%5C%5C%5C%5CRightarrow%5C%20x%3D10)
i.e. For 10 sessions, the cost of the two plans the same.
