Answer:

21x,

where x = number of entrees

Step-by-step explanation:

appetizer choices: 7

choices for an entree: x

choice for dessert: 3

Total number of combinations:

7 * x * 3 = 21x

Since the number of choices of entrees is missing, the best answer you can get is 21x, where x is the number of entrees.

Replace x with the number of entrees to get your final answer.
