Answer:

a.   [tex]c = 9 + 0.5w[/tex]

b.   She'll pay $11.5

Step-by-step explanation:

Given

Base Fee = $9

Additional Fee = $0.50 per show

Solving (a): Find the relationship between c and w

c = Monthly cost

w = Number of shows

c = Base Fee + Additional Fee * Number of Shows

[tex]c = 9 + 0.5 * w[/tex]

[tex]c = 9 + 0.5w[/tex]

Solving (b): Find c if w = 5

[tex]c = 9 + 0.5w[/tex]

Substitute 5 for w

[tex]c = 9 + 0.5 * 5[/tex]

[tex]c = 9 + 2.5[/tex]

[tex]c = 11.5[/tex]

Hence, She'll pay $11.5
