Explanation
This problem tests the fundamental counting principle, which states that the total number of choices is equal to the product of the independent choices. Let the number of sauces be represented by the variable S.
The total number of possible pasta dishes can be represented by each separate choice multiplied together: (8)(4)(S), or 32S. The problem also indicates that the total number of pasta
dishes must be equal to 320. Therefore, 32S = 320, so S = 10.
