To find the unit price of the turkey per pound, you need to divide the total price by the total weight in pounds.
The package weighs 1 1/4 pounds, which can be converted to an improper fraction:
1 1/4 = 1 + 1/4 = 4/4 + 1/4 = 5/4 pounds.
The total price for the package is $9.
Now, divide the price by the weight:
\[
\text{Unit Price} = \frac{\text{Total Price}}{\text{Total Weight}} = \frac{9}{5/4}
\]
To divide by a fraction, multiply by its reciprocal:
\[
\text{Unit Price} = 9 \times \frac{4}{5} = \frac{36}{5} = 7.20
\]
So the unit price of the turkey is $7.20 per pound.
Thus, the correct answer is:
**D $7.20 per pound.**
