Explanation:

Step1: Analyze Store W's equation

Store W has the equation $c=10$, which is a horizontal line where the cost $c$ is always 10, regardless of $n$. This line will intersect the $c$-axis at $(0, 10)$.

Step2: Analyze Store Z's equation

Store Z has the equation $c=0.60n+1$, which follows the slope-intercept form $y=mx+b$. Here, the y-intercept (c-intercept) is $b=1$, so it crosses the $c$-axis at $(0, 1)$. The slope $m=0.60$, meaning for each increase of 1 in $n$, $c$ increases by 0.60.

Step3: Match equations to graphs

We need a graph with a horizontal line at $c=10$ and a line starting at $(0,1)$ with a positive slope. Graph B has a horizontal blue line at $c=10$ and a red line starting at $(0,1)$ with a gentle positive slope, which matches both equations.

Answer:

B
