Question 976448: A health club charges non-members $5 per day to swim and $9 per day for an exercise class. Members pay a yearly fee of $300 plus $4 per day to attend an exercise class and no swim fee. If Robert swims and takes an exercise class every time he goes to the gym, which equation shows the number of days he must use the gym to make the membership worthwhile?

x=days
5x+9x=300+4x
10x=300
x=30 days
In 30 days, he will pay $14 a day for both without the program: That is $420.
With the yearly fee, in 30 days he will pay $300 + (30*$4)=$420.
