The store charges $4 to print each one-foot-long section of a banner that is three feet tall. Let x be the length of three-foot-tall banner. Then:

1. for 0<x<1, the price is $4;

2. for 1≤x<2, the price is $(4+4)=$8;

3. for 2≤x<3, the price is $(8+4)=$12 and so on.

The graph that satisfies these conditions is C.

correct choice is C.
