To determine the cost of admission for a group of 4 people at the amusement park, follow these steps:
1. First, recognize the function provided for calculating the cost of admission. The function is:
[tex]\[
C(p) = 30p
\][/tex]
where [tex]\( C(p) \)[/tex] represents the total cost in dollars and [tex]\( p \)[/tex] represents the number of people in the group.
2. Substitute the number of people in the group into the function. In this case, [tex]\( p = 4 \)[/tex].
3. Perform the substitution and calculate the cost:
[tex]\[
C(4) = 30 \times 4
\][/tex]
4. Now, multiply 30 by 4:
[tex]\[
30 \times 4 = 120
\][/tex]
5. Therefore, the cost of admission for a group of 4 people is 120 dollars.
So, the total cost of admission for a group of 4 people is $120.
