The constant of proportionality in the equation \( y = 15x \) is the coefficient of \( x \), which represents the price per ticket. In this case, the constant of proportionality is **15**, as it indicates the price of one movie ticket.
To find the total cost of the 5 tickets, you can substitute \( x = 5 \) into the equation:
\[
y = 15 \cdot 5 = 75
\]
So, the total cost of the 5 tickets is **$75**.
**Summary:**
- Constant of proportionality: **15**
- Total cost of 5 tickets: **$75**.
To find the total cost of the 5 tickets, you can substitute \( x = 5 \) into the equation:
