Answer:

$0.25 per pound.

Explanation:

Let us find unit rate for both quantities.

$\text{Price per pound}=\frac{8.75\text{ dollars}}{2.5\text{ pound}}$

$\text{Price per pound}=3.5\frac{\text{ dollars}}{\text{ pound}}$

Therefore, cost of per pound for first given rate is $3.5.

Now let us find unit rate for second quantity.

$\text{Price per pound}=\frac{9.75\text{ dollars}}{3\text{ pound}}$

$\text{Price per pound}=3.25\frac{\text{ dollars}}{\text{ pound}}$

We can see that price for second quantity is less than 1st. To find the savings per pound we will subtract 3.25 from 3.5.

$\text{Savings per pound}=3.50-3.25$

$\text{Savings per pound}=0.25$

Therefore, we will save $0.25 per pound by buying the least expensive.
