Answer:

Step-by-step explanation:
We have been given that Rachel sees a 10-pound bag for $5.90, a 5-pound bag for $2.75 and a 1 1/2 pound bag for $0.99. We are asked to find the lowest price per pound.
Let us find unit price per each bag.

[tex]\text{Unit price for 10 pound bag}=\frac{\$0.59}{\text{pound}}[/tex]
[tex]\text{Unit price for 5 pound bag}=\frac{\$2.75}{\text{5 pounds}}[/tex]
[tex]\text{Unit price for 5 pound bag}=\frac{\$0.55}{\text{ pound}}[/tex]
[tex]\text{Unit price for 1 1/2 pound bag}=\frac{\$0.99}{1\frac{1}{2}\text{ pounds}}[/tex]
[tex]\text{Unit price for 1 1/2 pound bag}=\frac{\$0.99}{1.5\text{ pounds}}[/tex]
[tex]\text{Unit price for 1 1/2 pound bag}=\frac{\$0.66}{\text{ pound}}[/tex]
