Step-by-step explanation:
Apparently the pressure formula is ...
__
a) A graph of this for f=261.63 is shown in the attachment.
__
b) The period is the time T required to change the sine function argument by 2π:
2πfT = 2π
T = 1/f . . . . . . divide by 2πf
The period is the reciprocal of the frequency.
The period of the tone is 1/(261.63 Hz) ≈ 3.822·10^-3 s

Answer:
The ticket increased 57% of its original price
The baggage price was 44.5 increased 0.11% and then became 50
Step-by-step explanation:
So if the amount was 200 and now is 350, we should use division.
200 ÷ 350 = 0.5714285714285714 which you can round to 0.57 or as many digits as the question asked for. In thise case I will use 0.57
0.57 converted to percentage is 57%
About the second question
now you know the amount after increase and the percentage. So all you have to do is reverse.
11% = 0.11
0.11 ✕ 50 = 5.5
this means the price increased 5.5
50 - 5.5 = 44.5
