To determine when both Sandra and Lady will bring cheese and crackers on the same day again, we need to find the least common multiple (LCM) of 6 days (Sandra's schedule) and 8 days (Lady's schedule).

Steps:

1. Prime factorization:

   • 6 = 2 × 3
   • 8 = 2³

2. Find the LCM: The LCM is found by taking the highest powers of all the prime factors:

   • Highest power of 2 is $2^3 = 8$
   • Highest power of 3 is $3^1 = 3$

   Therefore, the LCM is $8 \times 3 = 24$.

Thus, Sandra and Lady will both bring cheese and crackers again in 24 days.
