To find the unit price in dollars per pound, you divide the total cost by the total weight in pounds.
Total cost = $18.05
Total weight = 3.8 pounds
Unit price = Total cost / Total weight
Unit price = 18.05 / 3.8
Calculating that gives:
\[ \text{Unit price} = 18.05 \div 3.8 \approx 4.75 \]
So, the unit price is approximately $4.75 per pound when rounded to the nearest cent.
