Graph A

Explanation:

we need to find the slope using the slope formula y2-y1/x2-x1

Graph A:3-0/4-0

               3/4

Graph B: 4-0/4-0

                   1

Graph C: 5-0/4-0

              5/4

Graph D 8-0/4-0

                 2

These slopes are the cost per pound of apple and graph A has the smallest slope
