To find the cost for 1 pound of ground beef, we can use the cost of the beef at a given weight and divide it by the number of pounds.
From the table, we can take the cost of 10 pounds of ground beef, which is $37.50.
To find the cost per pound, we calculate:
\[ \text{Cost per pound} = \frac{\text{Total Cost}}{\text{Total Pounds}} = \frac{37.50}{10} = 3.75 \]
Therefore, the cost for 1 pound of ground beef is $3.75.
