In the sandwiches, mode select the "cheese sandwich" option and observe the equation given for the preparation of a cheese sandwich. in the equation, set the number of bread slices to "2" and the number of cheese slices to "1." you will see that the product formed by these three ingredients is one cheese sandwich. suppose you have 32 bread slices and 22 cheese slices. how many cheese sandwiches can you make?

we know that

one cheese sandwich--------> 2 bread slices+ 1 cheese slices
so
with
32 bread slices---------> (32/2)------> 16  sandwich 
then 
for 
16 cheese sandwich-------> 32 bread slices+ 16 cheese slices
 32 bread slices <= 32 bread slices (Quantity Available)------> is ok

and 16 cheese slices < = 22 cheese slices (Quantity Available)-----> is ok

the answer is
16 cheese sandwich
