Recipe calls for 2 eggs the class makes 18 recipes how many dozen eggs are needed

3 dozens

Step-by-step explanation:

If each recipe takes 2 eggs and we are making 18 batches of that recipe we can say that the total number of eggs we are going to need is 2 * 18 or 36 eggs.

In a dozen eggs, there are 12 eggs, so we can divide 36 by 12 to find the number of dozens we will need. 36/12 = 3

a. is correct
