Answer:
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
Answer: 7.5 lb
