<h2>Explanation</h2>
Subtract the total amount spent on groceries with what items you have prices for (in this case the gallon of milk):
$8.94 (total spent) - $4.29 (gallon of milk) = $4.65 (for 3 pounds of sliced turkey)
Next, divide the price for 3 pounds of sliced turkey with however many pounds Bonita bought (in this case, 3 pounds):
$4.65 (total for 3 pounds of turkey) ÷ 3 (pounds of turkey) = $1.55 (per pound of turkey)
<h2>Solution</h2>
Each pound of turkey costs $1.55
