Answer:
To find the equation relating C (cost) to P (number of people), we need more information. Please provide the specific equation or any additional details you have.
Once we have the equation, we can use it to find the cost of admission for 19 people. Simply substitute P = 19 into the equation and solve for C.
For example, if the equation is C = 5P, then we can calculate the cost as follows:
C = 5 * 19
C = 95
So the cost of admission for 19 people would be 95.
