A Correct answer
Explanation

Sum(M,T,W) = 44 * 3 = 132. Sum(T,W,Th) = 48 * 3 = 144. Since Th = 44, Sum(T,W) = 144 - 44 = 100. Then M = 132 - 100 = 32.

AI explanation

The total attendance for Monday, Tuesday, and Wednesday is 3 times 44, which equals 132. The total attendance for Tuesday, Wednesday, and Thursday is 3 times 48, which equals 144. Since Thursday's attendance was 44 and Monday's was M, the difference between these totals gives M minus 44 equals 132 minus 144, solving to M equals 32.
