Answer:
6
Step-by-step explanation:
5% of 120 were late
= 
× 120
= 0.05 × 120
= 6
That is negative since the elevator is decreasing. If the elevator was going up, it would be positive.
You must find the factors of each number...
9 = 1, 3, 3, 9
6 = 1, 2, 3, 6
Next, determine the common multiple...
9 = 1, 3, 3, 9
6 = 1, 2, 3, 6
Therefore, the most groups Lavinia can make without any glasses or mugs left to spare is 3.
I think the answer is A. Cause your supposed to subtract so 7n-4n=3n, and 3-2=1 :) I hope this helps
