Answer:
1. [tex]f(x) = 6x + 14[/tex]
2. $14 flat fee
Step-by-step explanation:
In this case, [tex]f(x)[/tex] where [tex]x[/tex] is time (hour). $14 dollar stays constant when [tex]x = 0[/tex]. This is the flat rate fee.
Let's do a sanity check:
[tex]f(1) = 6(1) + 14 = 20[/tex]
[tex]f(1.5) = 3(1.5) + 14 = 23[/tex]
[tex]f(2) = 6(2) + 14 = 26[/tex]
Looks like A. is the answer.
