A ball park charges an admission fee of 40 dollars for each person.

Question

Let C be the cost (In dollars) of admission for P people.
Write an equation relating C to P. Then use this equation to find the cost of admission for 13 people.

equation: _
cost for 13 people: _ dollars

Answer 1

The equation relating the cost \( C \) to the number of people \( P \) can be expressed as:

\[ C = 40P \]

To find the cost of admission for 13 people, substitute \( P = 13 \) into the equation:

\[ C = 40 \times 13 \]

Calculating this:

\[ C = 520 \]

Therefore, the cost of admission for 13 people is 520 dollars.

So the final answers are:

equation: \( C = 40P \)
cost for 13 people: 520 dollars
