At a deli 56 sandwiches were sold during lunchtime. twenty five percent of the sandwiches sold were tuna salad sandwiches. how many of the sandwiches sold

There was 14 tuna salad sandwiches that were sold. And there was 42 sandwiches that were not tuna salad sandwiches.

Since 25% of 56 is 14, 14 represents how many tuna salad sandwiches that was sold. And you do 56 - 14 to find out how many were not tuna salad sandwiches.

So 14 tuna salad sandwiches sold.

Correct me if I am wrong.
