Answer:
24
Explanation:
The first thing is to calculate the number of total sandwiches. We know that a dozen are 12 units, and there were 6 dozen therefore:
6 * 12 = 72
In other words, there were a total of 72 sandwiches.
Now to know how many chickens, they tell us that a third of the total are chicken, therefore you have to multiply that third by the total, 72. Thus:
72 * (1/3) = 24
In other words, there were 24 chicken sandwiches.
