Step-by-step explanation:
As given
In choosing this year 327 voted musical and 115 voted drama. 
 More students voted musical than drama = Total students voted for musical - Students voted for drama .
Putting values in the above
 More students voted musical than drama = 327- 115
                                                                       = 212 
Therefore 212 more student voted musical than drama .

Answer:
The mass of the radioactive sample after 40 minutes is 12.8 g.
Step-by-step explanation:
The mass of the sample can be found by using the exponential decay equation:

Where:
N(t): is the amount of the sample at time t =?
N₀: is the initial quantity of the sample = 120 g
t = 40 min
λ: is the decay constant =  0.056 min⁻¹
Hence, the mass of the sample after 40 min is:

      
Therefore, the mass of the radioactive sample after 40 minutes is 12.8 g.
I hope it helps you!
