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!

The lengths of these pieces are represented as follows:
shorter piece: s
longer piece: 3s
Then s + 3s = 24 ft, or 4s = 24 ft, or s = 6 ft.
One piece of wire is 6 ft long, and the other is 18 ft long.
You have to tell them what you think would happen to the earth if the sun disappeared.<span />
