Use the graph relations.

7.5 lb

Step-by-step explanation:

Look at the points on the graph.

She paid $1 for 1.5 lb.

She paid $2 for 3 lb.

She paid $4 for 6 lb.

She paid $7 for 10.5 lb.

Now divide each amount of lb by each cost.

1.5/1 = 1.5

3/2 = 1.5

6/4 = 1.5

7/10.5 = 1.5

In every case, she got 1.5 lb for each dollar.

On the day she spent $5, she got 1.5 lb for each dollar.

$5 * 1.5 lb/$ = 7.5 lb

7.5 lb
