Given the functions represents the cost of two companies A and B
[tex]A(n)=0.99+0.25n[/tex]And the cost of company B is given by the graph
We will check the options:
As shown the fixed fee for A = 0.99
From the graph, the fixed fee for B is greater than 1
So, the statement that must be true is b
The fixed fee for company B is greater than the fixed fee of company A
