First of all we will convert the pounds into ounces
1 pound = 16 ounces
20 pound = 20×16 = 320 ounces

To find out the no. of cookies we need to divide total ounce of dough by ounce of dough used by one cookie...
Therefore, The total number of cookies made by 320 ounce or 20 pounds of dough is 213...
