Answer:

36 days

Step-by-step explanation:

The goal is to list the multiples of both 12 and 9 to determine when they first coincide:

(a) 12, 24, 36, 48, 60, 72, 84, 96

(b) 9, 18, 27, 36, 45, 54, 63, 72, 81

The first multiple both numbers have in common is 36. Therefore, it will be 36 days before tacos and chicken are both on the menu again.
