Sagot :

SOLUTION

The cost per student =$5

Then let the total cost be C(n) and n be the number of students

Then required function is

[tex]C(n)=5n+30[/tex]

if the total number of student is 20, n=20

The total cost is

[tex]\begin{gathered} C(n)=5n+30 \\ C(n)=5(20)+30=100+30=130 \end{gathered}[/tex]

Then the total cost is $130

If the total number of student is 25, then n=25

The total cost becomes

[tex]\begin{gathered} C(n)=5n+30 \\ C(n)=5(25)+30=125+30=155 \end{gathered}[/tex]
