Question

An amusement park charges an admission fee of 30 dollars for each person.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 19 people.

Answer 1

The charge of admission fee for each person is $ 30.

The Cost of P people is C.

The equation relating C to P can be determined by using unitary method.

The cost of 1 person is 30

The cost of P person will be,

`\begin{gathered} C=30* P \\ C=30P \end{gathered}`

Thus, C=30P is the required equation.

The cost of admission for 19 people can be determined by substituting the value of P=19 in the above equation,

`\begin{gathered} C=30*19 \\ =570 \end{gathered}`

Thus, the required cost of admission is $ 570.
