Question:

The graph above shows the cost, in dollars, of apples as a function of the number of pounds of apples purchased at a particular grocery store. The equation above defines the cost C, in dollars, for p pounds of pears at the same store. Which of the following statements accurately compares the cost per pound of apples and the cost per pound of pears at this store?

A Apples cost approximately $0.07 less per pound than pears do.
Explaination

The cost per pound of apples can be determined by the slope of the graph as about $1.33 per pound. The cost per pound of pears can be determined by the slope of the line defined by the equation $9056_w60_h37.png$. The slope of the line defined by C is $8551_w9_h37.png$, so the cost per pound of pears is $1.40. Therefore, the apples cost approximately $0.07 less per pound than pears do.
