To find the cost per pound of cheese, you can divide the total cost by the total weight in pounds.
Here, Sandra pays $11 for 2.75 pounds of cheese.
Cost per pound = Total cost / Total weight Cost per pound = $11 / 2.75 pounds
Calculating this gives:
Cost per pound = $11 / 2.75 = $4.00
Therefore, the cost per pound of cheese is $4.00.
