Answer:
Step-by-step explanation:
If Workout gym has a $15 sign up and $1 daily fee and healthy gym has $5 sign up and $2 daily fee;
15a + 1b = 0
5a + 2b = 0
Since the sign up fee is constant, then a = 1; 15 + b = 0 and 5 +2b = 0
If b = 10, which represents 10 visits in a month, it is then ideal to visit the Workout gym if you plan on making more than 10 times monthly. If you plan on visiting less than 10 times monthly, then the Healthy gym is the better option.
