To find the total yearly cost at each gym based on the number of visits \( n \), we can substitute the values into the equations provided.

For Healthy Gym:
\[ t = 6n \]

For Fitness Gym:
\[ t = 50 + 5n \]

Now let's evaluate the options provided.

1. **When \( n = 10 \):**
- Healthy Gym:
\[ t = 6 \times 10 = 60 \]
- Fitness Gym:
\[ t = 50 + 5 \times 10 = 50 + 50 = 100 \]
- The total yearly costs are not equal.

2. **Total cost comparison:**
- As \( n \) increases, the cost at Healthy Gym increases linearly at a rate of 6 per visit, while the cost at Fitness Gym starts at $50 and increases at a rate of 5 per visit.
- Initially, when \( n = 0 \), the cost at Fitness Gym is already higher due to the $50 one-time charge. However, at higher values of \( n \), Healthy Gym will eventually become more expensive than Fitness Gym.

3. **When solving for \( n \) where costs equal:**
Set the two equations equal to find out how many visits lead to the same total cost:
\[ 6n = 50 + 5n \]
\[ 6n - 5n = 50 \]
\[ n = 50 \]
When \( n = 50 \):
- Healthy Gym:
\[ t = 6 \times 50 = 300 \]
- Fitness Gym:
\[ t = 50 + 5 \times 50 = 50 + 250 = 300 \]

Thus, the total yearly cost is the same at both gyms when members make 50 visits, not 10.

Considering these evaluations, the only statement that is true is:

**The total yearly cost is $300 at each gym for 50 visits.**
