Fatima paid a $50. initiation fee to join a gym. she also pays a fee of $25 per month. write an expression that shows how much fatima has spent after x months of membership at the gym.

When it says per month, it means to multiply. In this case, the expression would be;

25x+50 

So however many months Fatima has spent at the gym, you would multiply that times 25 and add the initiation fee. Hope this helps. 

The answer is 6 weeks
