Answer:
5
Explanation:
So as it says in the problem, Sarah spent $25 dollars to join a gym. Then she goes to these sessions each session is $5. At the end of the month, she ends up spending $50. So all you have to do here is add 5 to 25 until we get 50. However, 5´s you get, that's how many sessions she went to.
25+5 = 30
+5 = 35
+5 = 40
+5 = 45
+5 = 50
Once you count all of the 5´s, there are a total of five 5 which means she attended 5 sessions.
I hope it helps and have a great day!! :D
