On a snack tray there are 3 different types of crackers ( a dozen of each) and six different types of cheese ( a half dozen cubes of each). how many different combinations can be made.

18 combinations

Step-by-step explanation:

Assuming you can only have one slice of cheese per cracker, then you would have to multiply the number of types of crackers by how many types of cheeses there are to find the total amount of combinations.

3 crackers * 6 cheeses = 18 combinations
