Answer:

[tex]\large \boxed{C = 4n + 20; \$100}[/tex]

Step-by-step explanation:

1. Set up the expression

          Let C = the total cost of admission

          Let n = the number of students

     Then 4n = the cost for those students, and

              20 = admission cost

and 4n + 20 = total cost of admission. Then the expression is

                C = 4n + 20

2. Solve the expression

If n = 20,  

C = 4(20) + 20 = 80 + 20 = $100

[tex]\text{The total amount is $\large \boxed{\mathbf{\$100}}$}[/tex]
