The costs of cookies at Store A are shown in the graph. The cost y for x cookies at Store B is represented by the equation y = 0.30x. Which cookies are cost more, the cookies from Store A or the cookies from Store B? 

• Store A, because cookies are $0.25 each at store A and $0.30 each at Store B
• Store B, because cookies are $0.25 each at store B and $0.30 each at Store A
• Store B, because cookies are $0.25 each at store A and $0.30 each at Store B
