Answer:
120th caller
Step-by-step explanation:
120 is the common number by 40 and 30. trust me on this I'm really good at this subject in math.
To justify the yearly membership, you want to pay at least the same amount as a no-membership purchase, otherwise you would be losing money by purchasing a yearly membership. So set the no-membership cost equal to the yearly membership cost and solve.
no-membership costs $2 per day for swimming and $5 per day for aerobic, in other words, $7 per day. So if we let d = number of days, our cost can be calculated by "7d"
a yearly membership costs $200 plus $3 per day, or in other words, "200 + 3d"
Set them equal to each other and solve:
7d = 200 + 3d
4d = 200
d = 50
So you would need to attend the classes for at least 50 days to justify a yearly membership. I hope that helps!

Answer:
x=x
Step-by-step explanation:
3x - 2 = 3 (x - 2/3)
3x - 2 = 3x - 6/3
3x - 2 = 3x - 2
- 2 - 2
3x = 3x
/3 /3
x = x
